server, browser (forums): Redesign of the forum feature: Forum has been fully redesigned, it now uses pubsub relationships and pubsub extended discovery to handle the hierarchy. Categories lead to topics (which are the name of the items of a blog-like nodes). Topics have comment nodes which are used to show the topic messages. Subscription state is retrieve when a thread is shown, and can be changed easily with as ingle button click. Quill editor is used, and is extended with Quill-Mention to easily send a mention to an XMPP entity. Attachments and tags are handled with buttons added to Quill editor. Search in a thread is using Pubsub MAM, is the same way as for blogs. rel 463
