Move selection operators of Clip Editor into their own file

2D stabilization didn't work since clip start frame commit

Internal refactoring of tracking module, should be no functional changes

- Re-arrange functions in headers and implementation file to make them
more grouped by entity they're operating with. Also order of functions
in implementation file should match order of functions in header for
easier navigation.

- Rename some functions to match conventions of naming public functions.
- Some code de-duplication, still some room for improvements tho.
- Split main 2D tracking functions into smaller steps to make it more clear.

Accidentally OpenMP was disabled in some of previous commits, re-enable it.

Fix cycles non-progressive integrator not delivering correct AO pass.

SVN maintenance.

Comment no longer accurate.

Added option in shift-g to select verts by number of connected edges (valence).

click dragging with the eye dropper now averages out colors - useful when you have grainy footage of a green screen.
