No resize_widget function available

[TheFreeman]

Hi,

i included the latest jquery.gridster.with-extras.min.js.
But, there are missing some functions on my gridster-object in DOM.
E.g. there is no gridster.resize_widget() available:
TypeError: gridster.resize_widget is not a function
But others are there. What´s the matter?
Resizing is enabled in the config/options.

Best regards.
