license header year range adjustments

- changed targetting, to launch an airstrike move the cursor/pointer to a location and then press the firebutton - added a caption to try to explain this -_-

-Fixed FingerHasMoved function, still might need a little tweaking -Fixed targetting, it's not possible to fire airstrike and the like with a longpress, however it'll fire on the cursor not on the tap location

remove last boolean keys references and using only ParseCommand in uTouch now

various comment tweaks/fixes

MapModel: add getters for random maps based on type, so that the mapContainer does not have to magically know how maps and separators are ordered within the model

fix for issue #186 ("Screen gets messed up when selecting Hand Drawn Map")

unbreak snowball

Ok, 20,000 was a bit much. Arbitrary multiplier that seems to shove things off enough.

MapModel: comments/docs, small tweaks
