Added support for compressed x files (all files from dx sdk, except car2.x, work, no further tests yet).

Added a working makefile for mingw, provides more configs now. Not perfect yet.
Added decompression part of zlib (inflate).
Moved IrrXML to ./contrib dir.
Moved some IRR/IRRmesh shared code.
FIXME: makefile for gnu/linux is untested yet.
Code cleanup.
Unified #ifndef ASSIMP_BUILD_nnn_IMPORTER directives.
OBJ loader supports map_bump, map_ka, map_ks, map_ns now.
Endianess conversion in the ply loader is correct now.
Changed IRR/IRRMESH coordinate system conversion. Not absolutely right now, but better than before.
