Changes to "Face Select" mode

* Does not indicate that UV's exist, nor does it add UV's when used.
* Only accessible for texturepaint, vertexpaint and weightpaint from a button in the header (Paint Selection Mask)
* Not accessible from the mode menu, this is only an option that applies to paint modes.

This dosnt effect DNA, face select (G_FACESELECT) can be enabled at any time but is only used when paint modes are enabled.

Other changes
* UKey is uv unwrap in editmode, Ukey for undo was editmode only anyway.
* UVCalc in editmode adds a UV Layer if there is not one alredy.
* texture draw in editmode does not draw the face dots (they are get in the way of texturing)
* some missing updates were added.
* removed manipulator from when paint modes are enabled since the manipulator is not drawn in the 3d view.
