Fixed the build tags for the alt database engines.
Tweaked the quotes on the PgSQL adapter. Still not functional.
Removed the SQLite build tag as it's unlikely that it'll ever be implemented.
Added support for temporary bans.
Moved the Gosora specific template logic out of main.go and into template_init.go
Added an internal temporary group API.
We now use h1s in the theme headers. There may be some issues with the themes other than Shadow which we may need to resolve.
Added ARIA attributes in a few places for improved accessibility.
Added support for inputs in links for the .edit_field API.
Removed a few unneccesary prepared statements.
