Update ROI example to demonstrate removal

Merge remote-tracking branch 'fabioz/fix_widget_dead' into develop

Merge branch 'clear_cycles' into develop

  - Corrected isQObjectAlive for PyQt and older PySide
  - Warning messages are opt-in using pg.setConfigOptions(crashWarning=True)

PlotDataItem downsampling calculation fix

Added check for zero ViewBox width when calculating automatic downsampling ratio. (Prevents zero-division when downsampling is set before Plot is properly created and drawn within a container).

Added several utilities and debugging tools
Merge branch 'multiprocess-fix' into develop

Multiprocess debugging messages now use one color per process
Corrected RemoteGraphicsView not setting correct pg options on remote
process

New debugging tools:
* util.cprint for printing color on terminal (based on colorama)
* debug.ThreadColor causes each thread to print in a different color
* debug.PeriodicTrace used for debugging deadlocks
* Mutex for detecting deadlocks

Make sure we don't leave view boxes alive by doing a 'bridge' for the on the plot items. Also added warnings if proper cleanup wasn't done.

Merge branch 'make_scipy_optional' into develop

Several examples still require scipy.

Merge remote-tracking branch 'zarch/bottleneck_range' into develop
