Banners! Woo!

+ Error message banners on the top of the page. An upcoming update will
make the banners interactive.
Danger Danger, INDEV

+ Code reformed for some testing.

Note: This INDEV page will never be meant for public viewing, it is
simply a test page. Often a redirect will be used to forward viewers to
the 502 page when attempting to access the INDEV page.
Woo! Larger Text!

+ Adjusted welcome text to be slightly larger.
+ Added support for temporary banners (non-interactive).
