Changes to Tags in Tempo

We need to make an adjustment to how Tempo handles tags in order to squash a bug that keeps popping up on some users. Basically, we’re only going to allow tags to contain letters, numbers, hyphen and underscore. Any other characters (like parentheses, +, and *) will be converted to underscores automatically.

If you enter sys+admin as one of your tags you will get sys_admin instead, which we think isn’t so bad, really. This change will be going into production tonight.
