Script work

Add Envelope script
Add Clips and Boundaries Scripts.
Add docimages_oddments.py for the weirder cases.
Add make html script.
Add more spectral images
Add Dark versions of spectrograms (paul's comment)
Clean up oddments script.

- 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.
