Updating CivCraftSite

Went over CivCraftSite and updated a few things, tidied up, and generally tried to improve it.

Point by point:
* Replaced Bitcoin widget (broken) with a simple text area with the Bitcoin address in it.
* Restructured the HTML of the carousel template so it's not in one horrid lump.
* Converted the jade files to HTML and removed the jade dependency. This should reduce the barrier of entry to users who wish to help update in future.
* Finished the rules page, added to menu.
* Removed 'Online Players' (broken) from homepage.
* Moved infographic images linked by PrisonPearl, Citadel, JukeAlert on the index locally.
* Moved fontawesome CSS dependency locally.
* A load of tiny UX tweaks.
* Added a small README noting little quirks I found.

Do believe I am missing the Doge Coin donation address. I can add that if it's commented here.
