rdanbrook b8e4f1f501 The homebrew module
The homebrew module offers configurable ports useful to homebrew game
developers.

By reading and writing to new ports at configurable addresses, a rom may
* write to stdout
* write to stderr
* exit the emulator with a given exit status

These can be used to create automated test suites.
