Various Fixes

Headers for Main Forum View/Thread View/Thread List/Edit/Reply pages are
now set at 70px. The other views have not been changed as I want to
refactor those further anyway.

Changed portrait grid view on the main forums page to have a dynamic
width. It should now fill the entire width when snapped to any size.

Changed Unicode encoding again. When you edit/quote a post, it should
decode the HTML entities to show you the actual characters, rather than
the entities themselfs. Now you should be able to edit any language
without having to deal with hex characters.
