wxGUI: remove separators which just take space from toolbar

There were separators separating individual buttons (too dense)
and also one separating the combo box from the rest
(might have been actually useful on some plaftorms where
buttons have shades and combox boxes small borders).

Results is one button shorter on Ubuntu with Unity.
