fixed the math on the radial menu to display with the first item at 12:00, with subsequent items showing up clockwise
added mouseclick/release handlers to the character select radial menus
fixed a bug with mouse release handlers where they wouldn't work on a moved layer
fixed the math on the radial menu again
removed parameter passed to HideCharacterStats since it should not matter which character to hide, as there should only be one at a time
Added the concept of a state map to the battle, since i had begun to notice that there were clearly defined states that impact what UI controls are available
deselected character if you click on the currently selected character
