2.5: Space Image ported back

Organized as follows:

uvedit/
	uv editing related code
	uvedit_draw.c: drawing code
	uvedit_ops.c: operators, just a few done
	uvedit_unwrap_ops.c: will be operators for unwrapping
	uvedit_paramatrizer.c: lscm/abf/stretch/pack

space_image/
	space_image.c: registration and common getter/setters
	image_draw.c: drawing code, mostly functional
	image_panels.c: panels, all commented out
	image_render.c: render callbacks, non functional
	image_ops.c: operators, only view navigation done
	image_header.c: header, menus mostly done but missing buttons

Notes:
* Header menus consist only of Operator and RNA buttons, if they
  are not implemented they're displayed grayed out. Ideally the full
  header could work like this, but std_libbuttons looks problematic.

* Started using view2d code more than the old code, but for now it
  still does own view2d management due to some very specific
  requirements that the image window has. The drawing code however
  is more clear hopefully, it only uses view2d, and there is no
  switching between 'p' and 'f' view2d's anymore, it is always 'f'.

* In order to make uvedit operators more independent I move some
  image space settings to scene toolsettings, and the current image
  and its buffer is in the context. Especially sync selection and
  select mode belonged there anyway as this cannot work correct with
  different spaces having different settings anyway.

* Image paint is not back yet, did not want to put that together with
  uvedit because there's really no code sharing.. perhaps vertex paint,
  image paint and sculpt would be good to have in one module to share
  brush code, partial redraw, etc better.
