Replaces the tagline on your blog with a random tagline selected from a taglines file you provide.
Version 1.2 adds diagnostic information to the settings page.

<h3>The Tagline File</h3>
The tagline file should contain all of the taglines you want to randomly select from. It is return-delimited, ie. there is one tagline per line.
