Fixes #5

Implement .pk3 exporting

See merge request !12

* Uses the miniz library (https://github.com/richgel999/miniz).
  * The library was modified to deprecate .zip data structures that were not supported by the game.
  * The library was also modified to crate a new function solely for the purposes of kartmaker, removing redundant function calls. For more info, see "mz_zip_writer_init_file_kartmaker" in miniz.c
* Replaces the ability to export to .wad altogether.
  * To this end, lump.c and lump.h from Lumpmod were removed from the program.
* Skin graphics lumps, as well as the S_SKIN soc file, are located in "skins/[charactername]/". Sounds are in "sounds/skins/[charactername]/"

Also removed annoying prop line from README.
