Updated to XenForo 1.2.1

XenForo 1.2.1 fixes a number of bugs and issues that were in 1.2.0. As this is a maintenance release, the vast majority of the focus was an increase in stability. However, we have also made a few other improvements:

Moderators that have the "bypass user privacy" setting will now see when a user is banned. The username will be struck out in most cases.
There is now a rebuild cache tool to update trophies for all users. This will award any unawarded trophies and recalculate the trophy point totals.
There is now a rebuild cache tool to upgrade promotions for all users. Normally, promotions would only be run against active users. This tool will run the promotions against all users. This is mostly only relevant when adding or changing promotions and you want to ensure the changes are applied immediately.
There is now improved logging of fatal PHP errors. They will be logged with the other server error logs in the admin control panel.

Most of the changes are bug fixes. Some of the bugs fixed include:
