image paint

 Added two new blend modes to image painting brushes, erase alpha and
 add alpha, for painting transparency in images. When using the eraser
 tool of a tablet pen, the erase alpha blend mode is activated.

Old feature request: undo system now restores images without reloading.

 Was surprisingly easy to add, compiant with file reading and undo code.
 
 Currently only the Image->ibuf gets restored, and its opengl binding, so
 for realtime texture it works nicely. Also texture images are not freed
 inbetween undo steps
 
 Notes:
 - Painting textures will just keep the painted image, there's no undo
   yet for that
 - If this works satisfying, I'll extend it to compositing previews
