The user can now change their password in the Piccolo Admin UI (courtesy
sinisaos).
After submitting a custom form with Piccolo Admin, the UI used to show the
response message in a popup at the bottom of the screen. It now shows a success
page instead, which is better if the response message is long, as it's easier
for the user to read. Thanks to ethagnawl for reporting this issue.
