Patch/window handling (#468)
* Do not wrap PlotView/ImageView

There is no need to wrap PlotView/ImageView into QMainWindow, since
only purpose of the QMainWindow is some default menu toolbar & menu
handling, that is not used by PyQtGraph anyway.

Moreover, every parent-less Qt widget can become window, so this
change just use PlotView/ImageView as windows, removing extra
complexity, eg. method forwarding, self.win property.

Another benefit of this change, it that these windows get initial
dimensions and titles as they were designed in .ui file.

* Properly cleanup on ImageView.close()

We should not close explicitly child widgets or clear scene, otherwise
Qt will deallocate children views, and cause "wrapped C/C++ object of
type ImageItem has been deleted" error next time we call close()
and/or some other methods.

All children, including self.ui.roiPlot, self.ui.graphicsView will be
closed together with its parent, so there is no need to close them
explicitly.

So the purpose of close it to reclaim the memory, but not to make the existing ImageView object dysfunctional.

* Remove references to plot & image windows after close

PyQtGraph images and plots module list variables are currently holding
references to all plots and image windows returned directly from main
module. This does not seem to be documented however, and causes the Qt
windows to be not released from memory, even if user releases all own
references.

This change removes the references from images/plots list once window
is closed, so when there is no other reference, window and all related
memory is reclaimed.

* Change all UI forms title from Form to PyQtGraph

Date axis item (#1154)
* Add DateAxisItem

* Change style to camelCase

* Fix missing first tick for negative timestamps

* Add ms precision, auto skipping

Auto skipping allows a zoom level to skip ticks automatically if the
maximum number of ticks/pt is exceeded

* fixes suggested by @goetzc

* workaround for negative argument to utcfromtimestamp on windows

* attachToPlotItem method

* default date axis orientation

* Use new DateAxisItem in Plot Customization example

* attachToPlotItem bugfix

* examples of DateAxisItem

* modified description of customPlot example

* added descriptions to the new examples, reformatted their code, included the first one into utils.py

* typo

* Refactored code for setting axis items into new function

Replaces "DateAxisItem.attachToPlotItem"

* Fix string comparison with ==

* Doc: Slightly more text for DateAxisItem, small improvement for PlotItem

* Make PlotWidget.setAxisItems official

* Fix typo in docstring

* renamed an example

* merge bug fix

* Revert "merge bug fix"

This reverts commit 876b5a7cdb.

* Real bug fix

* support for dates upto -1e13..1e13

* Automatically limit DateAxisItem to a range from -1e12 to 1e12 years

Very large years (|y|>1e13) cause infinite loop, and since nobody
needs time 100 times larger than the age of the universe anyways,
this constrains it to 1e12.

Following suggestion by @axil:
https://github.com/pyqtgraph/pyqtgraph/pull/1154#issuecomment-612662168

* Also catch ValueErrors occuring on Linux before OverfloeErrors

While zooming out, before hitting OverflowErrors, utctimestamp
produces ValueErrors (at least on my Linux machine), so they
are also catched.

* Fix: Timestamp 0 corresponds to year 1970

For large years, x axis labels jump by 1970 years if it is not
accounted for timestamp 0 to be equal to year 1970.

* Fix: When zooming into extreme dates, OSError occurs

This commit catches the OSError like the other observed errors

* Disable stepping below years for dates outside *_REGULAR_TIMESTAMP

2 reasons: First: At least on my Linux machine, zooming into
those dates creates infinite loops. Second: Nobody needs
sub-year-precision for those extreme years anyways.

* Adapt zoom level sizes based on current font size and screen resolution

This is somewhat experimental. With this commit, no longer 60 px are
assumed as width for all zoom levels, but the current font and
display resolution are considered to calculate the width of ticks in
each zoom level. See the new function `updateZoomLevels` for
details.
Before calling this function, overridden functions `paint` and
`generateDrawSpecs` provide information over the current display
and font via `self.fontScaleFactor` and `self.fontMetrics`.

* Meaningful error meassage when adding axis to multiple PlotItems

As @axil noted in the DateAxisItem PR, currently users get a
segmentation fault when one tries to add an axis to multiple
PlotItems. This commit adds a meaningful RuntimeError message
for that case.

* setZoomLevelForDensity: Refactoring and calculating optimal spacing on the fly

* DateTimeAxis Fix: 1970 shows when zooming far out

* Refactoring: Make zoomLevels a customizable dict again

* updated the dateaxisitem example

* Fix: Get screen resolution in a way that also works for Qt 4

This is both a simplification in code and an improvement in backwards compatibility with Qt 4.

* DateAxisItem Fix: Also resolve time below 0.5 seconds

* unix line endings in examples

* DateTimeAxis Fix: For years < 1 and > 9999, stepping broke

Stepping was off by 1970 years for years < 1 and > 9999,
resulting in a gap in ticks visible when zooming out. Fixed by
subtracting the usual 1970 years.

* DateTimeAxis Fix: Zooming out too far causes infinite loop

Fixed by setting default limits to +/- 1e10 years. Should still
be enough.

* improved second dateaxisitem example

* 1..9999 years limit

* DateTimeAxis: Use OrderedDict to stay compatible with Python < 3-6

* DateAxisItem: Use font height to determine spacing for vertical axes

* window title

* added dateaxisitem.rst

* updated index.rst
