Implement repr() and str() for ByteBuffer

Browse Source 
I'm not sure using a hexdump makes sense for str() here, but I don't know what
else does yet.  I also know that I want a buffer to be hexdumpable, although I
think I'd prefer something that allows a hexdump not to require a huge amount
of memory.  Until we start processing HFS, I don't need to dwell on that too
much.  Let's get it working first.
