$data parameter not used in any of the 'get' functions

The request() function takes a $data parameter that adds a query string to the request and can be useful for things like increasing the number of tickets you get from a ticket report: http://unfuddle.com/docs/api/tickets#tickets

This isn't being used by any of the 'get' functions aka 'getTickets'.
public function getTickets($projectID = NULL)
should be:
public function getTickets($projectID = NULL, $data = '')

Will update this in both versions if no one has any objections.
