[ZPT] escaping chars in tal

This is a rare and therefore somewhat obscure effect of tal:define and
tal:attributes allowing multiple parts.  Since the parts are separated by
semicolons, any semicolon appearing in an expression must be quoted by
doubling it.  Thus:

tal:attributes="content python:('%s;; URL=%s' % (here.refreshrate,
here.absolute_url()))"
