Fetch the User-Agent String and Save as User Meta

Some times a client will complain that their site doesn’t look right or something equally as vague. Inevitable we ask “What browser are you using?” but getting the answer can be tricky. So, let’s just automatically get their user-agent and save it where we can access it.

Granted, this isn’t perfect. The client could have just logged in from someone else’s computer, and it is possible to fake the user-agent… but I’m counting on this being rare.
