parseDT only uses the magic json.Unmarshal method if theres an error
with the better version. Error came from some times being sent without a
"Z" at the end denoting UTC.
web UI now uses modules, and relies less on bodge to make things work.
Also fixes an issue where invites where "failed to send to xx" appeared
in invite form.
i wanted to split up the web ui components into multiple files, and
figured it'd be a good chance to try out typescript. run make typescript
to compile everything in ts/ and put it in data/static/.
This is less of a rewrite and more of a refactoring, most of it still
works the same but bits have been cleaned up too.
Remaining javascript found in setup.js and form.html
