If we don't do that, the default options get mixed up with theme modules (including our own theme_bootswatch).
Even worse, when installing any theme (including theme_bootswatch), the menu to change these options is replaced by the new theme one, so you cannot disable the broken options.
This trick allows theme modules to disable the default options so they don't conflict, while restoring the user choices when uninstalling the theme.
website.snippet: The methods described in javascript will be called automatically from the data-method_name = value on li snippets options. The methods are called in the order relative to children of xml (eg: <li data-method1=value1> ... <li data-method2=value2> ... </ li>, the method1 is then called method2). Methods receive two arguments: type (over, click, reset) and value. data-snippet-id-option becomes data-snippet-id. Several xml options can use the same data-snippet-id.
