Controller Support Improvements
- Added Controller options to Settings menu
- Holding the right shoulder button now triggers target selection via the right stick
- Pressing the right stick now opens a radial context menu in-game, enabling different actions based on selected target
- Added an alternate control scheme, allowing selection of targets via right stick instead of using a cursor
- Added an alternate spell control scheme, "Cast on button release", which uses left stick targeting
- Various additional controller behavior improvements
