bumping up allowed length of group_type column in group_types table from 100 to 400. Adding a subject in dotlrn with a 100 length subject pretty_name would break otherwise (the group_type becomes department key + subject pretty_name)
fixing bug 273 by making sure that the dotlrn users admin page doesn't non-dotlrn users that haven't verified their emails yet (they need to verify their emails to complete their registration before they can be added to dotlrn)
we want all links of the navbar to be active if we are not in a dotLRN instance (for example when we are at /pvt/home to be able to reach the MySpace page)
Fixed bulk-mail: The form didn't work because it didn't carry forward the 'group' variable. And the query to get the sender email got more rows than you wanted, due to a bad join.
