Fix scons compile after last commit ( unwanted new line )
Cycles OSL: fix mistake in recent refactoring, parameters are not set before setup.
Better removal of  \n in hash with rstrip
Correction to previous commit

Better just use "strip", to be sure \r\n is also stripped.
This also corresponds to what happens with popen() results.
File Browser: autocomplete keeps focus in the file field when entering a folder.

There is a bunch of internal refactoring going on too:
* No longer use operators to handle these directory and file fields, only makes
  things more complicated than they should be.
* Handle autocomplete partial/full match deeper in the UI code
* Directory field still does not keep focus, that's for another time to fix,
  you can already do pretty quick keyboard only navigation with the file field.

Move 2.6x versioning code to own file

Summary:
Makes readfile.c more clear and easier to navigate in.
We would need to do such a move when we'll do 2.70 bump
anyway. So better be prepared.

In fact, as soon 2.70 bumo is done i would think we'd
better create versioning_270 file and do version code
there. Otherwise readfile.c will grow up dramatically
again.

Image wrapping for plane track in clip editor

Summary:
Now it's possible to assign an image to plane tracks
in clip editor. This image is only used for display
in clip editor and this image is being warped into
the plane track rectangle.

Main purpose of this is to get early feedback about
how good image warping matches the footage, before
clip goes to the compositor.

Pretty much straightforward change: just compute
homography from undeformed normalized frame corner
coordinates (unity square) to plane marker corners
and apply this matrix to opengl stack.

Still could improve behavior when perspective
plane transform is degenerate, but that's not so
much critical for now i'd say.

Remove some extraneous glEnableClientState/glDisableClientState. This
part of the code is not interleaved with immediate mode drawing so they
are not necessary.
