Handle <pathauto> more usefully in custom_breadcrumbs 1.5

custom-breadcrumbs-pathauto.patch

This patch applied to Custom Breadcrumbs 1.5 and affects the way it processes
breadcrumb links when the user specifices `<pathauto>`: rather than cleaning
the whole path with *pathauto* (and thus killing any slashes), it passes *each
component* through.

Note that this is a bit of a hack: a robust implementation would clean the
substituted values as the path is being built. As it stands any `/`s in the
substituted values will remain in the output.
