Issue: vbSEO integration

We thought it would be a good idea to try to make VaultWiki work a little more smoothly on forums with vbSEO installed. While the options for vbSEO integration will not be very diverse, some features will be incorporated where available.

Needed to create a proxy file for simple URL pass-through, to redefine the script, and modify the URL structure throughout the wiki - meaning a lot of templates have been changed.

Got showpost permalinks functioning in a basic capacity, and hardcoded a number of workarounds to get some features working that vbSEO had broken. The linkback menu has been added to the drop-down for the article title, as well as to the comments tab.
