This tries to make our code a bit more compliant with our code formatting
conventions. For future use, this is the command I used:
git ls-files "*.cpp" "*.h" | xargs sed -i -e 's/[ \t]*$//'
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)
