This patch aims to implement the session management available on OS X.
Currently applicationShouldTerminate is just a go through that closes
everything and ends the application. The new implementation calls
first appCommitData and cancels the termination properly if required.
This means that if a user wishes to logout, Qt applications can now
cancel that like e.g. answering to Safari asking whether it is ok to
close because of a number of opened tab/window.
