This should be fairly cheap and pops off items if needed.

The table was generated using the old code. A table lookup
should be faster than lots of math and branches.

Allows us to drop `nextrange()` as well.

Allows rotating things like signs and torches. Axis rotation
rotates over all 6 faces, face rotation flips upside down to
flat on floor only, and of course in the 4 horizontal directions.

Made the code a bit more modular to account for different rotation
schemes. Should be easier to extend from here on to other needs,
and the functions can be reused by other mods for convenience.

Usage and tool break sounds were played at 'pointed_thing.above' which
can be nil if not pointing at anything or at an entity. This caused
sounds to be played to all players on a server non-positionally.

Fallback to player pos for sounds if 'pointed_thing.above' is nil.

Replace 'pt' variable with 'pointed_thing' in 'register_tool'.
