A whole lot of things I didn't feel like making separate commits for... I know.

- Added VU bars for Win-6 and paino rolls for Win-7
- Wins now start at 1 instead of 0.
- Instruments now show up in the bottom line
- Resizing the terminal doesn't break everything
- Proper clearing
- Removed the auto-centering because it sucked
