User/Person admin list view: add email_tag_filter_strategy and allow filtering by that and display_tag_filter_strategy
fixed an issue with email alerts when there are no tags in the alert subject line
More admin improvements:
* added created_by column to Tag list
* added columns to User table to show what tags the user is interested
  in, wants to ignore, and is subscribed to
* allow searching by object_id in Activity list
* show UserProfile in admin
Fixed bug in debug where 'message' is not a string, plus include a
timestamp in the message.
Fixes to send_email_alerts to ensure that:
* an user is always processed by the correct site
* we handle unexpected exceptions by emailing the exception details and
  the username to the admin, and then continuing on to the next user
* also, for now, lets print detailed logs for all users, not just
  WaterAid

Improvements to Post admin list view.
Fixed up/down-voting for non-empty .post-vote elements. In other words,

up/down-vote to happen, whether that element has child elements or not.
Renamed the imgClassAnswerVote variable because it relates to both
Questions and Answers.
