Melee range

Rewrites the majority of melee talents to check the talent's range field instead of hardcoding the distance.
This involved:
- Actually giving a range to talents that didn't have one.
- Replacing the range check with a call to canProject(tg, x, y)
- Moving many hardcoded tg values into a target field, and using getTalentTarget instead.
- Adding an is_melee and is_special_melee (shields) flag to talents (unnecessary, but potentially useful).

Also made it easier to have talents replace the Attack talent, like double strike.

I've run a character up through level 15, but otherwise haven't done much testing.

Upvalue slowdown

That seems to improve loading times by roughly 5 seconds on my toaster.

tableSample

(Based on another MR, sorry) added tableSampleIterator and stuff in Actor.lua now actually uses a bit of both.

Map effects can update once per game turn instead of once per base turn; all following map effects now use this for more precision

now iterCallbacks that yields callback, priority, kind, so you can safely ignore everything but the first.
