Embed angelscript

[SaintWish]

We have decided we should switch to angelscript because it has some much needed features and natively supports classes. That, and it's pretty close to c++ which will be better for us since we no longer have to learn a new language.

To do:

• [ ] script packer should compile scripts to byte code for release and non release should just pack the scripts.
• [ ] write compile script function on the game side.
• [ ] embed some classes
  • [ ] CMSMonster
  • [ ] CGenericItem
  • [ ] CBaseEntity
  • [ ] CFile
• [ ] embed some utility functions.
• [x] implement string
• [ ] compile lib for Linux.

This will be done in the as branch then merged once ready for release.
