[Desktop13.04-Topic] improve ubuntu-system-service or look at systemd services

[Sebastien Bacher]

Hey,

That's another potential topic, we currently still ship a "revert 
dropping of datetime helper" in our gsd package because we don't have a 
service providing timedated [1]. We should probably review what other 
services are in this case and either decide to implement those in 
ubuntu-system-service or to start using the systemd implementation of 
those (they are independant of the init system)...

Cheers,
Sebastien Bacher
