Update v1.1a

This update adds side quests to level 1, and also some smaller things.

All old saves are incompatible. Your hats and settings will be fine, though.

New Features:
-Added 3 Side Quests to Level 1. Each quest will grant you 1500 points, and getting all 3 will grant you a hat.
(Disclaimer: Quests for Level 2 and 3 will be added in a future update.)
-You can now check your side quests by pressing "C". Only works in levels with side quests available.
-Added 8 new paintings, plus 5 extra paintings made by some cool people.
-Added a couple easter eggs.

Fixes/Changes:
-Speedrun Clock is now more precise.
-Fixed HUD shake being broken if you have more than 200 health. (not possible without cheating)
-You can now change the ":)" in the advanced box settings.
