The old input code was getting too messy. A redesign made it easier to modify and add several modes and combos, including one for 1st person games which benefit from a different control scheme. A combo switches between the modes. I also added directional support while the virtual keyboard is visible, using the nub. This allows moving around in the text in some games, and moving the character while typing for others (e.g. AGI) svn-id: r53042
