Main menu with settings credits and game launching!

I finally undertook the process of making the menu. Unity makes it really easy to make UI but getting graphics settings to work took a while. When I first implemented changing graphics settings, the outcome is the complete opposite. If you choose the Horrendous preset, you get maxed out settings and vice versa. I fixed this by reordering options. I also added fullscreen as a toggle and a resolutions dropdown.

I also modified the gamemanager and the menu to allow for loading a robot from the main menu. It works by saving your robot index to a playerprefs, and gamemanager loads that corresponding robot. The scripts for camera management and robot enabling and disabling are all modular, so everything works smoothly!
