(that one mostly works but the textfield is not refocused).
This patch fixes both.

Also update MathCaptcha so that it works with recent versions of

which used to send the question in plaintext.

Also, drop the legacy createacct naming, except for the one
that is actually specific to CreateAccount.
The following patch must be merged immediately after this:
