Support for loading Windows + OS/2 BMP files.

1, 2, 4, 8, 16, 24 and 32 bpp
Uncompressed, RLE4, RLE8 and Bit Field compression modes

Handles V3, V4, V5, OS/2 v1 + v2.x, and various truncated headers.

TODO(Jeroen):

Right now all images are returned as 24-bit RGB. The core:image options to extend to RGBA (and use alpha where present) could be added, but RGBA bitmaps are very rare and not well supported (in other software).
Add support to write 24-bit or 32-bit BMP with V4 header and default bit fields for 4-channel images, V3 header for 3-channel images.
