Rename game_unpacker.dat to unpackclass.pack for consistency

game_unpacker.dat is the name of the file when downloaded in the
.jagex_cache_32/runescape directory. However, the other files containing
code are all named after the files on the web/JAGGRAB server.

This commit uses unpackclass.pack for consistency with all the other
files.
