Markov-Music-Shuffler

Missed a tab, and the fact that the genres are already sorted (replaced TreeMap with LinkedHashMap).

Replaced tabs with spaces.

Updated readme to have more information on the Markov chain file. Made the shuffle loop less ugly and cluttered. Stopped using a Hashmap+sort, now simply use TreeMap; fixed lack of alignment with genre input. Changed genres to be all caps to limit duplicates. Made default Markov chain to be evenly distributed.

Fixed some vagueness in the readme and instructions in the code.

Fixed a few bugs in rare cases, and updated synchronization. The GUI isn't the right size on Ubuntu, and I'm not sure why.
