This function should be called to initialize the preferences and
variables dictionary when libsaria is started. This function triggers
the POSTSTARTUP event.
I combined various parts of the Ocarina 4.0 event system into one file.
The new event file has threading abilities built in, so I no longer need
an external file for that
I revised the Ocarina 4.0 map class so it will hopefully have better
performance. I also began working on a new testing system so testing
specific changes should be easier than with Ocarina 4.0
