Zane Bitter fdcf6f8a3c Allow raw templates to be updated in the DB
Note that although this raw_template_update_template() will get called at
least every time the stack changes state (so twice for each operation), the
performance cost is negligible: we use the context's session, so the get()
will just retrieve the session's cached object, and we don't issue the
write unless the template has actually changed.
