Gameplay improvements

[CanYouSmellWhatRockIsCooking]

Add an option to the config which gives one an ability to disable and enable your exclusive gameplay improvements (the thing with movement points and boat, especially).

Great point.

For now I know only 3 improvements: the digging and boat movements and the last is quick combat.

The Quick-combat I cannot remove it easily though as I required multiple changes but for the other two I will add an option.
