brainfuck: Java

Man, my Java-fu is getting weak -- first time I've written Java in over
3 years! I used to know this stuff by heart...

The method for getting character input hasn't been implemented because
it's late and I don't really feel like mucking around with Java
anymore tonight.
objc: Handle loops by counting brackets

Tests now work!
objc: Don't count new lines as EOF

Technically new lines aren't EOF, and the program should continue
accepting input until EOF is reached. That means that to terminate the
program, you either have to hit ctrl-d, or run it like so:

    $ echo 'testing' | ./brainfuck ../tests/rot13.bf

The Python version implements the exact same behavior, which is how
I believe it is supposed to work.
