+I have create a patch to tag.pm for add the option for auto create tag pages.
+A new setting is used to enable or disable auto-create tag pages, `tag_autocreate`.
+The new tag file is created during the preprocess phase. 
+The new tag file is then complied during the change phase.

+A quirk I have not figured out is during the `sub change`, see my comments in the code.
