Issue was no access rights on blog.tag, add ability for all users to
read them, and for "knowledge" users to edit them.
Also fix pre-existing access rights and move them to knowledge users,
not users in general.

document_page is now contained inside website_blog, last part of the refactoring before
cleaning and improving the blog feature. Usefull files have been transfered.
Translations have been discarded, they will have to be re-translated again.
Document_page module is now dead. Long live website_blog!
Misc:
- some fixes in website_blog and wizard
- commented some sections of yml tests because they should not apply anymore
- added empty files for python unit tests in website_blog
