Update 0.12 - Optimization and Video Settings

I've looked through the discussions and reviews and fixed some of the more pressing issues. Keep the feedback coming! • Objective arrow is now always displayed infront of enemies • Fixed the damage scaling bug when using the Double Swords • Various optimizations that should hopefully alleviate some lag during late-game • Fixed wrong descriptions on upgraded Movement speed runes. • Added a small menu for adjusting video settings. Will likely get more complex options in the future. • Character hitbox reduced slightly in size
