/**
* Executes this controller, and return an {@link SS_HTTPResponse} object with the result.
*
* This method first does a few set-up activities:
* - Push this controller ont to the controller stack -
* see {@link Controller::curr()} for information about this.
* - Call {@link init()}
* - Defer to {@link RequestHandler->handleRequest()} to determine which action
* should be executed
*
* Note: $requestParams['executeForm'] support was removed,
* make the following change in your URLs:
* "/?executeForm=FooBar" -> "/FooBar"
* Also make sure "FooBar" is in the $allowed_actions of your controller class.
*
* Note: You should rarely need to overload run() -
* this kind of change is only really appropriate for things like nested
* controllers - {@link ModelAsController} and {@link RootURLController}
* are two examples here. If you want to make more
* orthodox functionality, it's better to overload {@link init()} or {@link index()}.
*
* Important: If you are going to overload handleRequest,
* make sure that you start the method with $this->pushCurrent()
* and end the method with $this->popCurrent().
* Failure to do this will create weird session errors.
*
* @param $request The {@link SS_HTTPRequest} object that is responsible
* for distributing request parsing.
* @return SS_HTTPResponse The response that this controller produces,
* including HTTP headers such as redirection info
