macosx: added an option to the crash reporter to disable the submission of the default email address

Now that we have a one instance mode with DBus under linux, also make
it possible to use the "one-instance-when-started-from-file" and
"started-from-file" options.
Consider using --started-from-file in the file association scripts,
like what we do in the win32 NSIS script, so that all files opened
through the GUI are enqueued/played in the same instance.

Saves a few kB and prevents some, ehm, corruption.

Inital patch by Marian Durkovic.

Once again, thanks to plc5_250 for the tests.

Thanks a lot to plc5_250 on IRC for testing.
