compositeMethod: introduced LumaMask

Introduced CompositeMethod::LumaMask that converts the source pixels to the
grayscale (luma value) before alpha blending. Thanks to it, mask works more like
typical mask in graphics editor software.
Grayscale is calculated with  weighted method:
(0.0721*B + 0.7154*G + 0.2125*R) * A
Introduced surface->blender.lumaValue function
