Merge lp:~ted/unity/systemd-unit. into lp:unity

[Ted Gould]

Adding systemd user session units

[Marco Trevisan (Treviño) (3v1n0)]

There have been changes recently to upstart job to change COMPIZ_CONFIG_PROFILE depending on the gfx environment. So please sync with upstream changes on that.

Also, please rebase on lp:~azzar1/unity/unity-active-plugins--safety-check, which will need to be ported too
