Image Stamping patch by Diego (and peach request)- stamps image info into metadata and optionally

draws into the
frame.

This patch includes some changes I made...   
* use blenders bitmap fonts (rather then own fonts)
* select font size
* user interface layout changes
* Marker as another image stamp option

Also added some new API calls   
BMF_GetFontHeight(font);
BMF_DrawStringBuf(...);  - so we can draw text into an imbuf's image buffer.
get_frame_marker(frame) - get the last marker from the frame.
IMB_rectfill_area(...) - fill in an image buffer with a rectangle area of color.

TODO - draw stamp info in 3d view, at the moment it just displays in the animation.
