Masking support for motion tracks

Browse Source 
Added option to use Grease Pencil datablock as a mask for pattern
when doing motion tracking. Option could be found in Tracking Settings
panel.

All strokes would be rasterized separately from each other and every
stroke is treating as a closed spline.

Also added option to apply a mask on track preview which is situated
just after B/B/W channel button under track preview.
