Rename to generichelper
Redo labels to contain more info on what is being done
Rewrite manpages to reflect better the new full helper system
Add:
	- guesshelper - which takes an action type (edit, view, play - the
	  	latter two being synonyms) and a filename, and tries to guess
		the best action type to use, depending on filename extension
		and possibly output from /usr/bin/file - configurable,
		and finds what action/filetype this should give to
		generichelper
	- guessedhelper - takes an action type and a filename, and calls
	  	guesshelper to find what label to use, then calls
		generichelper
