Mikael Nordfeldth 0612e5ec87 NewnoticeAction converted to extend FormAction
There are still several improvements which can be made, such as not
having an entirely separate setup of ajax form functions. Instead
those should be implemented in FormAction. But at least now we got
rid of the redundant code use in prepare/handle.
