* Use libertine-lxc-manager when starting/stopping a container for libertine-container-manager operations if the session DBus is available.  If not, fallback to l-c-m starting/stopping the container. (LP: #1628587)
* Add a new entry to ContainersConfig for keeping track of running processes in a container. (LP: #1632729)

* Split out Xmir helper apps into their own package.
* Add support for starting pasted and matchbox for snap based/ containerless apps in U8. (LP: #1637535)
* Add implementation for libertine gui as a system-settings plugin. (LP: #1623946)
* Manually require archive name during archive configuration.
* Add a warning to the top of ContainersConfig.json advising users not to edit the file.
