Social media share match

Here is an small update to allow players to share their matchs with friends.
Changes:

1. matches are public now (you dont need to login to see them)
2. social media buttons are now displayed after statistics

Pros: 
- You can share your match in facebook and show your friend how you destroyed him in a test match. Other people will see it and would like to join too. Everything is funnier with friends

Cons:
- Social icons could be a little intrusive and maybe annoying.

You could also check if the viewer is not logged in and display a pop out message saying something like "Are you part of OpenSoccer already? If not, JOIN NOW" or something like that.
