Order of buttons in *SelectorContext not consistent with the rest
The order of the Apply and Cancel buttons in *SelectorContext (lists, trees and tables) is reversed to the order in the rest of the TL.
The order should be adjusted and the mechanics for this should be outsourced to a utility class in order to be able to change it again more easily later.
Test
Open the dialog for creating an attribute in the base administration. It is expected that the order of the buttons there matches the order in the diaglog for selecting the type.
