v0.3.6

• Fixed Python Editor crashes (memory trashing).
• Made Python Editor remember its text when closed and reopened.
• Fixed Python Editor's coloring sometimes getting mixed up.
• Improved Python Editor's tabulation when a colon ends the line
  (to handle for, def, class, etc).
• Fixed Color Panel that had gotten broken due to adding python.
• Added a contactSheet.py demo for showing all the layers of an OpenEXR image or
  sequence in Compare Tile mode.
• Fixed Compare Tile mode selection and unselection of multiple clips in Compare Panel.
• Made cmd.compare() use the item index instead of item itself to avoid
  confusion when the same file was loaded more than once.
• Made CompareMode be part of the media module instead of the timeline module.
• Made mrv2 exit cleanly once the process calls _wexecv on Windows.
• Fixed the bad release of mrv2 v0.3.5 on Windows which would open a command
  console on start up.
• Fixed Compare Panel selection when paths were the same on two clips (ie. same
  video or image loaded several times).
• Fixed a zombie process being left on Windows exit.
