Set the SBApplication instance's sendMode to kAENoReply to speed up how quickly gitx terminates

Without this it was waiting for the Apple Event to respond, which could result in the gitx command line app staying open for a few seconds as it waits for the reply. This happened frequently when trying to open a repository that was already open.
