"write" functions to get data from a "const" buffer. Added an "write" functions to get data from a "const" buffer. Added an

improvements by Gregory S. Read. Added PHYSFS_[us]int(8|16|32)
types...this breaks binary compatibility with previous PhysicsFS
releases! Added platform specific i/o functions, so we don't have
to rely on stdio anymore.
