Ported the format.h/cpp to be C compatible and fixed other files
accordingly
Started porting image.h
Converted image.h/.cpp to C and implemented the input stream system
Implemented image.cpp completely, ported colour_conversion.h/.cpp
Removed the return values of HILL_image_read*; you had to know them
already to allocate enough space in dst
Made the C version compile; Note that it does not work yet
Implemented JPEG support (CHILL WORKS NOW! YAY!)
Replaced self->cinfo.src by cinfo->src since they are equal; Unneeded
stuff is now 'unread' from the input stream.
Added PNG support! Fixed HILL_image_open segfaulting when file did not exist
Added BMP support!
Added TIFF support!
