(svn r10996) -Feature: [OSX] added more options for right click emulation (controlled from the interface tab in the patch window)

This only works with the cocoa drivers (you will use the cocoa drivers unless you manually switched to SDL and compiled yourself)
  Note: if control-click is selected, then the ingame control-click (like presignals and such) will be command-click
  Requested and tested by ln- (so he should be blamed if this goes wrong :P )
