Fix #155 (After create a permalink and reload, only two dimension elements are selectable)
Fix #157 (Deselect and selectAll Buttons are still usable in deactivated state)
Fix #156 (After change data set the "i am working"-notification does not disappear)

Something went wrong with display-property of $("#cubeviz-dataSelectionModule-spinner"),
i have no idea! After slideDown the spinner, a slideUp does not work.
So slide was replaced by fade.
