Add level cap to other practice method.
Add level cap to construction tasks.
Remove unnecessary turns argument from skill methods.
Forces vehicle::of_turn to zero upon load rather than leaving it
undefined.

Normally this doesn't matter because vehicle::gain_moves() will
clobber it when the map next updates all the vehicles. However, if the
player is driving really fast it's possible for a vehicle to be loaded
while the map is in the middle of updating the vehicles, where the
undefined of_turn was sometimes an issue.
Removes doubling effect from food-morale.

Fixes butcher message

The message 'There are no corpses here to butcher' no longer erroneously appears after 'You don't have a sharp item to butcher with' message is triggered.
Fixes curtain interaction from outside the building.
Fixes highlighting when view is shifted. (examine, open, close)
Print choose_direction() messages directly onto the w_terrain window to prevent problems with SDL redrawing.
Fix UI menu auto-hotkey assignment:

prevent lag by the loop when all possible hotkeys have been used up.
Use uimenu::addentry with a std::string as last parameter, not a const char*, as that would invoke the printf formatting.
