Found all remaining references to forem_avatar method, replaced with gravatar_image_tag workaround.
Made further changes to the navigation to ensure the user-facing routing information properly displayed case-specific titles.  Styling changes made to the new user registration page.  A topics controller decorator has been added to allow for game-specific character sheets to be loaded so character details such as the in-game character name and select attributes to be displayed along with the avatar.  Feature still under construction.
