Minor polishing to Hard difficulty:

- cleaned up a zigzag in intro
- mirrored a section after the first drop to remove unintended and slightly clunky thumbswitches
- revised ending to remove an unfair zigzag

If my understanding is correct, this update should wipe leaderboards for Hard difficulty, and only Hard difficulty.

Forgot to save the very last changes I made to the Hard chart, derp.

Hard difficulty charted. Might do another polishing pass on this chart, who knows.
