Weary State Check API Script for Roll20

A first-run at a script which automatically sets characters as weary when their endurance falls below their fatigue. This will change once the character sheets go online for everyone, as the names and values of things are likely to change.

	The One Ring weary-state setter for Roll20 API
	By Michael Heilemann (michael.heilemann@me.com)
	Checks to see if a character's endurance drops below her fatigue, and
	automatically sets the `weary` attribute to `weary` or `normal`, depending.
	This is very useful particularly if you're using the TOR roll tables, as you
	can then read the weary attribute of the selected token in a macro and roll
	on the appropriate success die table automatically:
	/r 1t[feat] + @{travel}t[@{weary}]
	It requires that the character have `endurance`, `travel_fatigue`,
	`encumbrance_fatigue` and `weary` attributes.
