Option for multiline transition events

[GoogleCodeExporter]

When I have a transition with event="streaming.quit dpad.up.held dialog.cancel 
back" that label is very long and cumbersome in the UI. It would be nice if 
there were an option to split event descriptors on spaces when displaying them, 
e.g.

streaming.quit
 dpad.up.held
 dialog.cancel
      back

This also makes it more obvious that there are multiple events and not one long 
event name.
