* Enhance speedRatio settings (#270#290)
This commit changes the way the mouse sensitivity works as follows:
1. Turn speedRatio into a QPointF, so we have two floats instead of
one integer.
2. Default the y-speedRatio to be x-speedRatio / 2.25, which takes
the ultra-wideness of modern phone screens into account.
3. Add new configuration value speedRatioX to allow users to
configure an individual X-ratio
4. Add new configuration value speedRatioY to allow users to
configure an individual Y-ratio
5. Optimze distance-translation a bit.
6. Add keymaps/FRAG.json using new speedRatioX/speedRatioY for the
game "FRAG! Pro Shooter"
