[Traverso-devel] Cursors

[ben levitt]

I just committed some cursor changes.  Here's a summary:
- <LeftMouseButton> and [LeftMouseButton] on the song view move the work cursor
- While transporting, moving the work cursor doesn't move the play cursor
- When not transporting, moving the work cursor hides the play
cursor, which reappears at the work location when transport starts
again
- dragging [SPACE] moves the playcursor (and shows it if it was hidden)
- zooming centers on the work cursor

I also made a few keymap changes:
- modified Alt-Z zooms out  :)
- clicking in a curve view no longer adds a node.  Now requires
double clicking.
- CTRL-LeftMouseButton now drags a clip copy, instead of CTRL-ALT-LMB
- dragging a marker and a curve node can be done with LMB
- disabled anchored dragging until I get a chance to clean it up some more

Remon: I definitely changed the feel of the app with these changes.
:)  But I think it feels a lot more usable this way.  If you feel
otherwise, please tell me, and I'll revert.  (But I'll probably still
try to convince you for a while first...)  :)
