Updated Login System / Menu Bar

[brian]

The Login System has been revamped. You can now login or logout from any page on the site. Just click on the small user icon below the date. If the user icon contains a green check mark, then you are logged in.

The Menu Bar has also been redesigned. You may not notice the difference, but it is no longer using unique images for each button. The buttons are created dynamically by the web site. This allows for custom menu items to appear depending on who is logged in. As part of this change, I was able to go from two separate templates (one PHP and one JavaScript) down to a single PHP template that can dynamically create the JavaScript version when needed. This saves time when adding or removing site components.
