Re: Circular dependency mess

This is an easy fix--you just move the import for plugin_utils until
where it's needed.

Generally, tools should be a leaf module--it shouldn't be importing
anything else in PyBlosxom.  However the run_callbacks situation breaks
that.

At some point, I want to relocate the callback stuff, but that's outside
the scope of 1.5.

Are you seeing other circular dependency issues other than this one?
