URL encoding issue when changing settings
This issue applies to usergroups that have a text input or textarea property.
Basically, when a user submits the Change Settings form and an error occurs
(e.g. passwords don't match), FEU redirects the user with a long raw URL
containing all the parameters for properties they filled out, and if they have
any special characters (such as ampersands or quote marks) in a property, they
get messed up due to the URL encoding and end up with something like this in the
