Fixed bugs in profiles + layout update

- couldn’t great a profile, because the form was hard coded to post to
the wrong URL
- When fixed, couldn’t pass the check, because the model had been
updated and the form had not - it was error checking for data that does
not exist.

While I was at it, I dealt with Jon’s request to display errors below
the fields, rather than next to them - saves on horizontal real estate.
Make last update work

Displays time in UTC, but it works.  Not sure why time zone conversion
isn’t working, but this is close enough for now.
