Converted the BitArray class into "BigInteger", replacing its clunky old arithmetic methods with a proper set of arithmetic operators so it can be used like an int. All the bit-access methods are still there, and there's a typedef of BitArray -> BigInteger to allow most old code to still work. (You might need to change calls to isEmpty() to isZero() though). Also fixed a bug in MidiBuffer.
