FIXED: Default site view updated for proper display and validation
FIXED: Required attribute in xml has a value of "required"

In HTML the input object has a required attribute whose only valid
value is "required". This was previously stored as a boolean value, but
now in order for proper validation must be stored as "required" or
"false".
FIXED: Errors are correctly displayed when form fails validation
FIXED: Changed for Notice: message in PHP
FIXED: Router will now redirect to correct layout with form id
