hcwiid: Library to interface with the wiimote

This is a refurbished version of hcwiid. It will include most of cwiid.
If you find something in cwiid which is not included here and you need it,
please let me know/send a pull request.

First things first: How the frag do I compile the tests in test/?

You need to do two things:
1) Compile the program with -rtsopts (enable RTS command line flags)
2) Run the program with +RTS -V0
   This will disable the internal ticks used for profiling, which
   in turn will make the runtime system not use the SIGALRM signal,
   which libluetooth uses for its own internal purposes and is necessary
   to connect to the wiimote.

   (This bit is the work of Paolo Capriotti, whose mastery of GHC
    baffles me every time.)
