-Created page type
------------------
-
-The interdiction to create pages of type po was broken by the new
-`page_types` code. This is fixed in my po branch by
-commit 1914ae2fd24e1e802.
-
-While I was there, I also added some code to set a new default value
-to the type select field in case it was previously set to "po".
-This code favors the type of the linking page's masterpage on page
-creation (when `from=page.LL`). This is commit c9301d2c296f682.
