Minesweeper enhancements (FS #7327, FS #7335, some further changes by me): * Make info splash display number of flags and number of mines. * Directions on iPod use Left/Right/Menu/Play now, with Select for flagging and long Select for exploring. Additionally, Scroll Left/Right goes left/right with wrapping to the previos/next line at the edges. * Make info splash work on Iaudios. * Swap main explore and flag buttons on recorder (and av300) to make them consistent with the other tragets and the rest of the minesweeper world. * On irivers, Rec can be used as an alternative for flagging, making one-handed playing easier on H1x0. * Removed unused macros.
