Generate Application.DocumentChange and Application.Quit events.

SfxHintId::DocChanged seems to correspond nicely enough to
Application.DocumentChange. It is generated a bit eagerly, but as its
documentation is fairly vague and no specific detailed information is
passed in parameters anyway, it probably doesn't hurt if a client gets
it a bit more often with LO than with some other product.

Can now remove the FIXME-marked Quit event things in SwVbaApplication.

Now need oovbaapi in many makefiles for them to compile.
