creating new revision of page.
Fixes an issue where editing a document.page and changing name and/or summary
(to create a new revision) also changes name and summary of the history_head.
draft_name and draft_summary are now computed fields (based on history_head)
but have set the inverse without actually setting the value, to allow setting
them when creating a new draft page.
The issue is prominently evident when using document_page_approval where
the name/summary for the new draft also change the last approved version
(aka history_head) which should not happen.
* move menus to a higher level.
* fix categories search view.
* fix create menu action not being accessible in any way.
* reorder form view, focusing in the content, not in secondary fields.
[document_page] FIX BUG: UI hanging when editing content. This was due to the api.depends on _compute_diff. Removing it because it's not really necessary since the field is not stored.
[document_page] page_id should be readonly.
