image sorting
	will affect:
		promote
		demote
		shift up
		shift down
		ribbon merging
add promote/demote events (to attach structure editors)...
add real images...
make all the code relative to the current selection (multiple instances on a page support)
make this into a jquery plugin...
add dynamic loading and unloading for very large sets...
gesture support...
add basic actions:
	rotate left
	rotate right
	...
add info:
	number of images in ribbon
	position in ribbon


first stage refactoring:
	merge almost identical functions...

multiple groups to promote/demote
	ways to go:
		promote/demote and tag

ISSUES:
	jumping on focus up/down...
	demoting a first element (a ribbon is created) positions the field incorrectly (see demoteImage() for details)...
