Create a team page for dlang, listing some frequent contributors to the project

I think D would benefit from introducing visitors to the website to who some of the people behind the language are.  I went through and found the top committers to dmd, druntime, and phobos and created a page with bios for them (some who would qualify for multiple projects, like Kenji, were only listed once), at least for those who talked at DConf before.  I don't know exactly who belongs on this page, this is just my guess.  Any beginning blogger is told to create an About page with their name, photo, and some info about themselves and while I don't think it's necessary for bloggers, it would help for a larger project like this.

More importantly, the review process for pull requests needs to be documented.  [I've created a stub page for this on the wiki](http://wiki.dlang.org/Review_process), the real details should be filled in.  Even if the process is as vague as "Some people look at your code and eventually one of the committers will merge it if good enough," it needs to be documented, so that contributors know what to expect.

There's been a lot of talk about professionalism, but that starts with the project leaders.  These types of pages should have been written a long time ago.
