Haiku Media Kit: new and old pieces

Hello, it has been some time since my last article, in the meantime I continued to improve things out and since I changed some important parts of the media_kit, I think it's correct to notify the community about new and 'old' features added recently. This is an article mostly written for application developers, but I tried to explain the improvements made with simple words so I hope it will be interesting to anyone.Of all the alternative operating systems from the golden days (2000-2005 or so), Haiku is one of the very few - possibly the only one - still going strong. And by "going strong" I mean seeing a ton of development seemingly without seeing a sort of definitive release. They're trying to reach zero by endlessly dividing by 2, it seems, getting ever so much closer to zero without actually getting there.
