Profile customization

[SoulRipper]

I've tried to improve the user profiles by allowing you to personalize it more than just your bio and some other basic info. I've made more fields you can fill in (optionally), I've added the ability to have your favorite Youtube movie/music on your profile and I added a message box for your profile visitors to write something, just like on your Steam profile. Last but not least you see the last 10 visitors to your profile.

For an example, I guess you should visit my profile or others who have personalized their profile already.

If you have any suggestions, for example more things to add, just say here and maybe I'll add it too.
