[PATCH v3 0/4] git-gui: Add ability to revert selected hunks and lines

Hi,

This series adds the ability to revert selected lines and hunks in git-gui. Partially based on the patch by Bert Wesarg [0].

The commits can be found in the topic branch 'py/revert-hunks-lines' at https://github.com/prati0100/git-gui/tree/py/revert-hunks-lines

Changes in v3:
- Drop the confirmation dialog on partial reverts. It is still there for
  full file reverts (which was the original behaviour).
- Allow undoing the last revert.
- Update the context menu button layout. In v2, the layout was:
   Stage Hunk
   Revert Hunk
   Stage Lines
   Revert Lines

  Now it is:
   Stage Hunk
   Stage Lines
   -----------
   Revert Hunk
   Revert Lines
   Undo Last Revert
- Return early when applying a patch fails. This is useful for this
  series because in that case we don't save a faulty patch in
  last_revert, causing the same error to pop up when reverting the patch
  that failed to apply in the first place.

Changes in v2:
- Add an option to disable the revert confirmation prompt as suggested
  by Johannes Sixt.
- Base the patches on Pat's git-gui tree instead of git.git.
