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

reimplement the quit engine+frontend keys

add ammoprop to enable to up and down buttons on for the touch interface

decouple current theme from map theme (fixes theme confusion bugs of last commit)

MapModel converted to QStandardItemList; separators fixed; changed used data format (human-readable struct instead of magic list) for map info in HwMapContainer (+ various small cleanups in that class)
