[arch-dev-public] merging systemd back to a singular package

Hi, I apologize for this being somewhat after-the-fact. It was discussed on IRC, but that of course doesn't necessarily cater to a wide enough audience. Some of you have probably already noticed that systemd 189 now provides, conflicts, and replaces libsystemd and systemd-tools. This is the next logical step since systemd will eventually be in base once we have sufficient unit coverage. As an added bonus, maybe this will encourage people who haven't switched over yet to do so. ;) Cheers, Dave
