* Loads a theme opening page - as stored in the "theme" session key. This is loaded for every

* needs to contain every file. Other themes can just define whatever pages they want to override
* and omit the others.
*
* @param string $template the location of the template file, relative to the theme folder
* @param array $page_vars a hash of information to provide to the template
* @param string $g_theme an optional parameter, letting you override the default theme
* @param string $g_theme an optional parameter, letting you override the default swatch
