Start moving client towards a more refined design

I'm splitting up core pieces of functionality into several smaller
modules. TrueCraftGame will be made smaller and smaller until it's just
a small wrapper around the modules doing all of the work. This should
allow for modders to easily add new modules or replace builtin modules,
and will make the codebase more maintainable in general.
