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.

We need to reimplement an on-the-fly option to record streams.
I know this commit is crappy...

Thanks a lot to ipkiss for providing the bisect builds and geal for his help.

One side effect is that the snapshot is now taken using the picture that
will be displayed (chroma and resize filter applied).

It will allow to have different procedures for osd subpicture and subtitle
subpicture.

( At best, a = b++ is not atomic)

This will slow a few complaints from many people.

Pretty please, remember to delete the file name in POTFILE.in when you delete them from git

This reverts commit 65052fef.
It's already taken care of in the for loop just before

Ogg can be now: ogx, ogv, oga but we have to keep ogg and ogm for backward compatibility.
