Fixes and updates in next/

Typo/format fixes were made in next/pw-change.html, next/register.html,
next/submit.html.

The screenshot for register step 6 (welcome email) was updated to
reflect a typo I had reported (after it was fixed). The html file still
has to be checked for rendering and that will be done soon.
