add virtual filesystem thing w/ ZIP support

Browse source 
similar to Quake 3: all the archives and folders get mounted to the same mountpoint in the VFS, read access to files in the VFS is transparent

/* tinfl.c v1.11 - public domain inflate with zlib header parsing/adler32 checking (inflate-only subset of miniz.c)
See "unlicense" statement at the end of this file.
Rich Geldreich <richgel99@gmail.com>, last updated May 20, 2011
Implements RFC 1950: https://www.ietf.org/rfc/rfc1950.txt and RFC 1951: https://www.ietf.org/rfc/rfc1951.txt
The entire decompressor coroutine is implemented in tinfl_decompress(). The other functions are optional high-level helpers.
