Adding basic transport controls. Right now the play/pause and restart buttons work. There's a 'next' button, but if we want to have one I'll need to store/get that information, which I currently do not do.
Now there are variables for the song's duration and current position. This is necessary for some song playback / restart stuff.
Added transport buttons to the optionsScrollView, but they're super basic at the moment.
Took a stab at the "flickering" issue but all I did was make a conditional in updateBubbles a little more clear/verbose (didn't fix the problem).
