Updated FAQ and new Supporters page

Since we have been receiving some emails with questions the last days, we updated the FAQ page (and arranged it in a neat way) , so it hopefully will answer your questions.
Still, if you have questions which are not answered by the FAQ, feel free to ask us by sending an email to developers@agilereview.org.

Additionally, in order to honor our users and supportes, the new users & supporters page shows all users (at least those we know of) and supporters of AgileReview. If you actively use AgileReview in your process and want to be named on this page, feel free to contact us.
