Added option to use "None" for adj in setData
This allows you to easily create code to toggle lines on or off by setting to the appropriate array if on, or None if off. Currently you have to have 2 seperate setData calls, one with adj and one without

arrayToPath: revert to old meaning of connect=ndarray parameter (#1461)
The i-th position of that array used to define if points (i) and (i+1)
were connected, but in master it defines whether points (i-1) and (i) are connected.
This commit reverts to (i) and (i+1) interpretation.

Fix TickSliderItem: Avoid ghost ticks | Improved customPlot.py code (#1459)
* Fix TickSliderItem: Avoid ghost ticks | Improved customPlot.py code

If `TickSliderItem.setTickValue` was called when a full repaint of the `TickSliderItem` was
not already scheduled, the tick was visible at the old and the new position. This could e.g. be seen
when using the autoscale button in the `customPlot.py` example.

Further, code from `customPlot.py` is improved to make use of `Tick.setVisible` instead of adding and
removing ticks based on their visibility.

Fixes for examples\customPlot.py (#1448)
* Fix examples\customPlot.py: Not object-oriented

Copy-paste error: I referenced a specific object instead of self. Fixed.

* Fix examples\customPlot.py: Allow calling setTicks more than once

This fixes a bug where TickSliderItem is expected to return ticks.keys() but while it returns ticks.items().
Also: Minor code correction.

* Fix examples\customPlot.py: Avoid scaling differences

Consider padding of TickSliderItem for link between ViewBox and ticks

TickSliderItem: allowRemove property added (#1442)
* TickSliderItem: allowRemove property added

Following #744, this PR suggests the addition of a property
`allowRemove` to `TickSliderItem` and therefore also to
`GradientEditorItem`. It sets the default of whether ticks can
be removed by the user and therefore contemplates `allowAdd`.

I would be interested in other opinions on this design decision,
as #744 suggests to reuse `allowAdd` for the prohibition of
tick removal.
I personally suggest this solution, since it does not change
the effect of the current API.

Fix #744

* customPlot.py: Added markers to example using TickSliderItem

* examples\GradientWidget.py: Demonstrate use of allowRemove

Fix ViewBox axis zoom in RectMode and examples/customPlot.py (#1443)
* Fix examples/customPlot.py: mouseDragEvent misses axis argument

Fixes #1277

* customPlot.py: Update methodolgy to disable menu

If there's an argument for this, we should use it

* customPlot.py: Show how to disable axis interaction

* Fix ViewBox: Moving axis in RectMode not implemented => use normal move mode

Grabbing an axis in RectMode leads to the zoom rectangle being displayed
in unreasonable positions. In this case, fall back to normal mode.

* customPlot.py: Only disable right-click zoom for demonstration

In cases where continuous zooming is not wished (e.g. in case of
complicated rebinning after zooming), this might come in handy
and there is no reason not to show it.

TickSliderItem: Use Tick.removeAllowed (#1441)
* Fix: TickSliderItem ignores Tick.removeAllowed

This prohibits removing ticks from a `TickSliderItem` if they were set to `tick.removeAllowed=False`.

Test code:
```python3
import pyqtgraph as pg
from pyqtgraph.Qt import QtCore
import numpy as np

app = pg.mkQApp()

class CustomWidget(pg.GraphicsView):
    def __init__(self, parent=None, *args, **kargs):
        pg.GraphicsView.__init__(self, parent, useOpenGL=False, background=None)
        self.item = pg.TickSliderItem(*args, **kargs)

        for pos in (0, 0.5, 1):
            tick = self.item.addTick(pos)
            tick.removeAllowed = False # Possibility 1

        # Possibility 2
        for tick, value in self.item.listTicks():
            tick.removeAllowed = False

        self.setCentralItem(self.item)
        self.setFixedHeight(31)

w = CustomWidget()
w.show()

app.exec_()
```

* Make 'removeAllowed' regular property of 'Tick'

Add "left" and "right" step Modes (#1360)
* Add "lstep" and "rstep" step Modes

stepMode is currently either True or False. If it is True,
it requires the user to make len(x) = len(y)+1. This is
inconvenient because it makes it difficult to change the
stepMode on a given curve (just as one would change, e.g.,
its color).

This commit extends the current situation by introducing
two more step modes: "lstep" and "rstep", which do not require
passing an extra x value. In turn, this modes associate each
y value to either the left or the right boundary of the step.

For example, the "rstep" mode is handy when plotting "life"
digital signals in which x,y data pairs are appended as they
are read.

This commit does not modify the behaviour in case of stepMode=True

* Replace step mode names: lstep,rstep -> left,right

* Improve docs for stepMode

Reword docstring and add it to PlotDataItem class too

* Document left and right stepModes as added in v 0.12.0

TODO: confirm the exact version number to use here

* Add comments stress the need for "is True"

Some conditional statements in the code regarding stepMode are
done with "is True". This is actually required since other
possible values such as "left" also evaluate as true but should
not be caught.

* Deprecate boolean API for stepMode

Introduce stepMode="mid" as a replacement of stepMode=True,
but keeping full backwards compatibility with the old API.
Adapt docs, examples and tests accordingly.

* Raise ValueError on unsupported stepMode values

* Rename "mid" step mode to "center"

* Remove "added in 0.12.0" note

See https://github.com/pyqtgraph/pyqtgraph/pull/1360#discussion_r502746919

* Add deprecation warning when stepMode=True

Issue a DeprecationWarning if stepMode=True is being passed to the
constructor or setData() of PlotDataItem or PlotCurveItem.

Note: warnings module is imported locally so that it is esier to
remove once this check is no longer needed.

* Fix wrong syntax in last commit

Fix usage of "default" kwarg in dict.get()
