UI add in elements

[Luke-Larsen]

This is going to be less based on the over all layout, but should still look good with the current design layout. We will be redesigning the website some time in the future, but for now we need to implement these elements.

• Add in a total signed-up user and users online
• Add in referrals to other sites like pivx.promo to make it, so users can explore the pivx-labs ecosystem.
• Add in a rank listing system for the most successful players
• Add in a recently finished game area to show information on previous games
• Research the possibility of a global chat system and check if it is something we would like to pursue.
