Somehow the MIPSpro compiler doesn't like an STL map entry being called using a variable when the reference is an object and not a pointer to an object. Preliminary support for a fontcache is added which prevents fonts from being loaded more than once and takes care of freeing them up again. The fontcache isn't used yet since there seems to be a problem somewhere.
