[PATCH] Seperate RMGen libraries to directory mp-team

[FeXoR]

Since most maps don't use the libs gaia.js and setup.js and to destiguish them more as a specific approach for random map generation I propose seperating them into another directory. That also avoids unneeded namespace flooding.

They are quite closely tied up so they will likely be needed both or none anyways.

Since some of the functions and the maps unsing them focussing on multiplayer teams I propose the name mp-team.

We might want to do this for other libs as well.
