Build 26311981

changes to opentest branch only.

update: for the time being gamepad controls are only officially supported on linux. this is because while linux correctly recognises my gamepad as a gamepad, windows does not, thinking it is a joystick. setting up joystick inputs still doesn't work since it doesn't correctly take in inputs correctly anyway. maybe more recent pc or console gamepads work fine but i can only test with what i have so have no way of guaranteeing gamepad support on windows.

started implementing gamepad controls, right now has a on-screen pointer in the main menu and generate planet scenes, can point (left stick), click (south button), rotate planet (right stick and triggers), and slide (left and right d pad), with speed buttons (bumpers). controller pointer also automatically disappears when using keyboard and mouse and reappears when using gamepad. added gamepad controls description to an options menu tab.
