made custom listener, but current implementation is a basic tooltip
tooltip expanded to actually display event info instead of just a test message, a little buggy, displays same time for start and end
Made tooltips fixed width to handle long descriptions.
Made desciption field only appear when description is present, added tooltips to day view.
Added color to background of info panels for events, changed color of text for displayed events and info panel to black or white depending on darkness of background.
