Mode select changes (read below)

Added DAS to the up/down actions (24F start-up, 6F period)
Added wheel scroll to the up/down/left/right actions
Added a warning in case somehow the player has no modes or rulesets
Mode select will load new modules every time you access it
However, this does not reload changes to existing modules
