decide_receiver($feedurl,$author,$question,$course,$policy,$defaultflag);

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
