- Moved Diggy skills onto main screen (instead of being in a panel in Diggy's scrolling list at the bottom of the screen) so they are always accessible/visible - Added support for pressing keyboard keys 1-6 to use Diggy skills - Changed to always show Diggy skill tooltips on skill buttons, even if the skill is locked - Fixed bug with 'time drift' when game is left open for long periods of time (usually 8+ hours, sometimes multiple days at a time)
