Simplify marseypatching for use with a scripting language

[Androclast]

Subversion was meant to be a more full-fledged solution to client modding and marsey to be a quick-patch solution.
Currently subversion overshadows it by doing its job and then allowing to add its own code to the game.

Marseypatching shouldn't require to have an IDE ready and should be redone into a scripting language like javascript or lua.
Integrating https://github.com/mynameundefined/Lua14 is one way to accomplish this.
