* Replaced compress/uncompress inline code (encode_zip/decode_zip) with the respective zlib library calls while keeping 3rdparty calls inside common code (follow up to r14888, related r14808).

 	* Changed grfio.c include order and moved zlib include from the header to the source. [FlavioJS]
 	* Merged decode_zip/encode_zip from eapp's grfio to replace our direct use of zlib's uncompress/compress.
