	Arguments
	$feedurl - /res/ url of resource (only need if $author is true)
	$author,$question,$course,$policy - all true/false parameters
	if true will attempt to find the addresses of user that should receive
	this type of feedback (author - feedback to author of resource $feedurl,
	$question 'Resource Content Questions', $course 'Course Content Question',
	$policy 'Course Policy')
	(Additionally it also checks $env for whether the corresponding form.<name>
	element exists, for ease of use in a html response context)

	$defaultflag - (internal should be left blank) if true gather addresses
	that aren't for a section even if I have a section
	(used for reccursion internally, first we look for
	addresses for our specific section then we recurse
	and look for non section addresses)

	Returns
	$typestyle - string of html text, describing what addresses were found
	%to - a hash, which keys are addresses of users to send messages to
	the keys will look like name:domain
