Support for obfuscated maps

[JarosLucky]

Stormfox 2, is able to correctly load maps with obfuscation, if the lump file is next to the source, to match the loader support, but.

If the lump file is only on the server, and the client does not have it, then the client will have errors.

for example one of them:
stormfox2/lua/stormfox2/lib/sh_mapglass.lua:646: bad argument #1 to 'pairs' (table expected, got nil)
