This should make it easier to find files and (in the future) split things up into separate libraries. It also changes around emulator initialization to make it a little more difficult to do things out of order and a little more sensible as to when real init work happens. Also adding a skeleton audio system/driver and reworking CPU register access to be more extensible.
