Change Formo field template to use named labels, turn on auto_id for fields.
The implicit labels <label>Foo<input ...></label> weren't cooperating with js.
So, we go back to <label for="...">Foo</label><input ...> and turn on auto_id
to maintain strict compliance ("for" must point to a CSS id, so we need them!).
Convert admin/server_add form to Formo.
Fix Formo override's auto-class-setting code for textboxes.
Fix use of ORM::changed() in Model_Task::save().
