Lots of new features an changes

The secuences have been redesigned:
-Now a secuence is being interpreted by an interpreter, causing the
controller being captured by it (impeding the player movement for
example).
-Also each interpreter has a specific functionallity (Dialogs,events and
checkables) making it very extensible.

New Features:
- Camera movement during dialogs. With a smooooth movement. So smoooth
:]
- Teleporters: Now entities can be teleported throught maps.
- Random movements: This entity script creates random movements in a
entitiy.
