/**
* This file concerns itself almost completely with theme administration.
* Its tasks include changing theme settings, installing and removing
* themes, choosing the current theme, and editing themes.
*
* @todo Update this for the new package manager?
*
* Creating and distributing theme packages:
* There isn't that much required to package and distribute your own themes...
* just do the following:
* - create a theme_info.xml file, with the root element theme-info.
* - its name should go in a name element, just like description.
* - your name should go in author. (email in the email attribute.)
* - any support website for the theme should be in website.
* - layers and templates (non-default) should go in those elements ;).
* - if the images dir isn't images, specify in the images element.
* - any extra rows for themes should go in extra, serialized. (as in array(variable => value).)
* - tar and gzip the directory - and you're done!
* - please include any special license in a license.txt file.
