Forum: Major redesign of forums: Forums have been redesigned. They follow the new general design with 2 or 3 panels, allowing to have directly a forum if one is found/set up, and a panel on the left to search/discover other ones. Categories have been rewritten to be usable with pubsub relationships, a XEP-0277 type node is used for topics, and each item has a comments node for the threads. The thread view is set in `forum/show_messages.html` template. It has a header with a search box and a button to (un)subscribe. Items are displayed with the same macros as for the blog items. Below a room is set for editor, tags and attachments. rel 463
