e0c22e2796 Adding some additional deprectated APIs for Qt5. Example plots (mostly) working. 
This adds some remaining APIs that were deprecated in Qt5. These are easy to do
as they're all documented, e.g.
http://qt-project.org/doc/qt-5.0/qtwidgets/qgraphicsitem-compat.html

Tested with most of the examples. Although I can't be sure as I
don't know what the 'correct' output is, they look like they work.

Some issues with interaction e.g. on the color bar plot.

42dbd7956a Adding PyQt5 compatibility (broken) 
Adding compatibility for PyQt5 via a shim in Qt.py. This restructures the PyQt5 libraries
to match the layout seen in PyQt4, allowing it to continue to be used as drop in replacement.

This works up to the point of importing, however other API changes are broken - for example
the deprectation of .scale() on GraphicsItems throws an error currently.

24cf9ada2c BF: unicode fix for TableWidget

  for pyside compatibility.

e8dd3e6e57 ImageItem.getHistogram is more clever about constructing histograms: 
- integer dtype images now have integer-aligned bins, with bin number
    determined by a target value
  - step size is automatically chosen based on a target image size
  - bins and step arguments have default values 'auto'

20b9d079ce Nicer range for value histogram of integer images. 
When an ImageItem's data has an integer dtype, this patch ensures that
each bin of the LUT histogram contains the same number of integer
values, in order to avoid "spikes" in the histogram that are merely due
to some bins covering more integer values than others.

This commit needs testing (it was rebased from an old commit).

f136b33033 Profilers controllable via PYQTGRAPHPROFILE. 
A new function profiling system is implemented.  Most importantly, this
allows one to profile various internal functions directly by setting the
`PYQTGRAPHPROFILE` environment variable to a comma separated list of
function and method names, e.g.

    PYQTGRAPHPROFILE=functions.makeARGB,ImageItem.render \
        python -mexamples

Specifically, items in `PYQTGRAPHPROFILE` must be of the form
`classname.methodname` or `dotted_module_name.functionname`, with the
initial "pyqtgraph." stripped from the dotted module name.

Moreover, the overhead of inactive profilers has been kept minimal: an
introspective check of the caller's name (only if `PYQTGRAPHPROFILE` is
set) and a trivial function (not method) call per profiler call.

The new profilers rely on `sys._getframe` to find the caller's name,
although the previous system (passing the caller's name explicitely)
could certainly have been kept instead.

Finally the API of profilers has been changed: register a
profiling point simply by calling the profiler, and profilers are
automatically flushed on garbage collection.  See the docstring of
`pyqtgraph.debug.Profiler` for more details.

The main change is on `ViewBox.getContextMenus`, which now returns an

Also, `getContextMenus` was given a default implementation in the base
class (falling back on `getMenu` if defined), and some cleanup was done.

58ed8ee7bd ViewBox overhaul. Cleaned up code pathway: 
- setRange now only affects target range
  - updateViewRange only affects view range
  - updateMatrix only affects childGroup transform
  - updateMatrix is only called before a render

Pathway now looks like:
        setRange -> updateViewRange -> matrix dirty -> ...
                                    -> sigRangeChanged

        ... -> prepareForPaint -> updateAutoRange, updateMatrix if dirty

 - AxisItem.setScale(float) has the usual behavior
 - AxisItem.setScale(None) is no longer allowed. Instead use:
 - AxisItem.enableAutoSIPrefix(bool) to enable/disable SI prefix scaling
Also makes the API more intuitive since these features are now accessed and implemented independently.
