Add Alternative Spellcasting Input Methods (such as keybinds)

I'd like to see other options for spell casting other than radial menus to spell swap. I personally can't stand radial menus in combat and it's put me off using spells all together. I wouldn't suggest scrapping the radial menu all together because I'm sure there are others who would prefer it, but I'd like to see key binding options to allow me to set casting each spell to a button. 1 = Cast spell 1, 2 - Cast Spell 2, 3 = Cast Spell 3. I think both options should exist to accommodate different playstyles with the option to disable the radial menu and set spells to a key of our choosing.
