fbx: more type/casts fixes for 64-bit windows
embed miniz.c from https://miniz.googlecode.com/
catch all fbx exceptions
tell inflate the expected output length
don't Z_FINISH in the first inflate round

miniz expects the output buffer to be large enough to handle the
complete result
optimize buffer handling if output fits in out_hint
Merge pull request #3 from stbuehler/fbx-dev

use embedded miniz for zlib stuff on windows
