beginings of a working touchscreen interface for the WPS. 2 new tags:

%T|x|y|width|height|action| <- setup a region (relative to the current viewport) where if pressed the "action" will be done (currently play/stop/prev/next/menu/browse work, suggestions for others to add and better names welcome)
%Tl<timeout> <- used as a conditional to say if the touchscreen was touched in the last <timeout>, use this to enable/disable button viewports or something... same syntax as other timeout tags

cabbiev2 for the mr500 has been modified to demonstrate the new tags. press the pause/play button to pause playback. press the rockbox logo to get back to the menu. pretty icons needed to make this more usable :)
