===========================
- Split clip hotkeys into two categories:
* Global
* Editing
This allows to re-use such hotkeys as track markers
from properties region without worrying about conflicts.
- Anchor point could now be offseted from marker position.
- Pattern can now be symmetrical relative to marker position only.
- Changes to mouse sliding:
* Left top rectangle used for marker position and now
it's half inside and half outside of marker.
* Right bottom corners are for size.
* Anchor point can be slided with mouse to adjust offset.
- Resolved conflict caused by left-mouse selection option.
Now it works perfectly with sliding -- no more "sticky" keys or so.
- Fixed some typos.
===========================
- Fixed incorrect mouse sliding when resizing area which isn't
symmetrical to marker's position.
- Added "Clip" group to User Preferences -> Input lust.
Now hotkeys can be investigated there and also, they can be changed there.

scripts/startup/ is now the only auto-loading script dir which gives some speedup for blender loading too.
~/.blender/2.56/scripts/startup works for auto-loading scripts too.
