GPencil: New option to lock strokes to axis

Now, the strokes can be locked to a plane set in the cursor location.
This option allow the artist to rotate the view and draw keeping the
strokes flat over the surface. This option is similar to surface option
but doesn't need a object.

The option is only valid for 3D view and strokes in CURSOR mode.
