Fixed the bad interaction between Cultists and Pyroclast events in the Daikara

Added engine support for gamepad events and touch events; no effect ingame but addons could be made to make touch or gamepad UIs

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.
