Set correct 'My Account' link after changing username

Don't print messages (and the account form) in process_account_form()
anymore, but return them to the caller. When updating accounts, this
function will be called before the headers are written.

If a username has been changed by process_account_form(), the headers
now show the updated username from the database in the 'My Account'
link. Clicking on it immediately after changing a username will no
longer lead to a non-existing URL.
