- This commit also adds an option NOT to bring Audacity to the top when screenshotting.
-- That's because QuickPlay will disappear if you do -because you lose mouse capture.
- Also allow negative window IDs in the drag command.

- Registration names of align commands sorted.  They had &, : and / in them.
- Fixed bug in SetTrackInfo where bFocused was being ignored
- Fixed bug where command manager ignored multi-commands.
- Commit docimages_oddments.py again, to fix line endings.
