An update of kcm_systemd to the latest upstream release, version 1.2.1. Changes:

1.2.1 (2015-08-08):

• A simple integrated editor is used for editing unit files. Saving is done through a KAuth action for proper authentication. This provides better security than the old method of calling an external editor using kdesu.
• Boost is only depended upon when using non-C++11-capable compilers (thanks to Johan Ouwerkerk).
• Use drkonqi for handling crashes (requires KF5Crash framework).
• Several translations were added.

1.2.0 (2015-07-02):

• Kcmsystemd is now hosted on KDE infrastructure and name was changed to systemd-kcm. (The license was also changed, from "GPL version 3 or later" to "GPL version 2 or later".)
• User units can now be viewed and manipulated.
• A tab for viewing timer units was added (similar to the command: systemctl list-timers).
• Systemd-kcm now respects the user's color scheme.
• Added support for HoldoffTimeoutSec and RuntimeDirectorySize options in logind.conf.
• Several translations were added.
