3 * Plugin to render old skool templates
5 * Captures rendered parts from the output buffer, passes them through a template file: tpl/index.html
6 * Adds an API method at index.php/template/update which lets you overwrite the template file
7 * Requires username/password and a single POST parameter called "template"
8 * The method is disabled unless the user is #1, the first user of the system
