Added program that parses DECORATE files

The program looks for actors and their states. Later this program shall be able to generate new monster actors inherited from these, whose death actions will reward the player with points.
Fixed small bugs in DECORATE parser
Finished proof-of-concept version of DECORATE generator

Each monster kill is now rewarded by 5 points and the new DECORATE files are written to disk. While awarding 5 points for every monster is not the goal it is a functional proof of concept that we will be able to generate updated actors easily with this tool.
