CSS/JS Updates

Cleaned up look of pages a bit; added focus to initial textbox on pages

Themes!

I've created a few themes. I use jQuery to set the theme path to
localStorage and in $(document).ready() I update the <link
id="themeLink"> tag to set it to the chosen them, which will persist
between reloads and logouts.
Themes update

Changed behavior so that the theme select box is set to the current
theme instead of "No Theme" if one has been chosen already.
