Manage Project Popup: more organized details + clickable website link

Making the background color of the website button match the popup's background color is a bit of a hack, there's probably a better way to achieve this.

It takes a little more space, but looks a lot better in my opinion. The dimensions of the popup could be increased to make up for that (or the default size of the entire application really, it's rather small).

Might also make sense to have this match the project details of a project on lib.haxe.org, which would include a `Version` and an `Owner` bullet point:
