Added initial config file framework.

Using Ogre::ConfigFile to read in the ini files that will configure Entity
types.
Add Entity configuration from the config file.

Yeah... I can't word it better than that right now.
Add Behaviour factory behavior from the config file.

I'm not from the UK... so don't blame me for spelling.
Update ini file to match our factory.

Might actually work now... Though the first entity might cause some issues
with its multivalue value (as in key=>value_list).
