PixelPaint: Introduce new mask features

Browse source 
This patch adds a new Editing-Mask type to layers. This kind of mask
is used to restrict changes on the content bitmap only to areas where
the mask is drawn. The intensity of a pixel change is controlled by the
alpha-value of the mask.

Furthermore a function to invert and clear masks has been introduced.
When a new mask is created for a layer the edit mode of the layer is
also changed to Mask so that the user can immediately start to draw the
mask.
