Issue #31: Tweaked the breadcrumb PHP, and corrected a block setting

The shared hosting at DreamHost wasn't working right with the PHP that I
had cobbled together to do the breadcrumbs for the chapel message views
(or vice-versa ha). This makes the '%1' contextual variable handle a little
nicer.

I also corrected the block setting which (it seems) wasn't getting exported.
