Added new image_cast method and added its bindings to python, added two new properities to images: offset and scaling. Added way to cast between image types with offset and scaling. Added new unit tests for color and casting. Made it so that pixel setting doesn't result in overflows or underflows. Made the return of get_pixel, dynamic based on what is passed to it. Added new methods for setting pixels that are doubles and ints.

Renamed background to fill, added numeric casting to fill utility, changed clog uses to MAPNIK_LOG, changed the implementation of fill some so that it only used a single template
