The current permission system nomenclature is inconsistent and this makes it difficult to make sure all the permissions are given according to the site admin's plan.

Examples:
"tiki_p_view": view what?

Blogs:
tiki_p_create_blogs
tiki_p_blog_post
tiki_p_blog_admin
tiki_p_read_blog

Why sometimes blog_action and sometimes action_blog ?

There are currenlty 141 permission items
