Add logind_support.patch

Port the logind_support.patch from gnome-settings-daemon 3.6 to allow lid switch
control to work with cinnamon-settings-daemon when systemd is installed
(as is the case with Docker).
Add quilt as a build dependency

Debuild complains about a lintian error from a missing build dependency for
quilt.
Merge branch 'fix-lintian-add-quilt-build-dependency'
Merge branch 'master' of https://github.com/linuxmint/cinnamon-settings-daemon
Merge branch 'master' into easier-fix-for-laptop-backlight-controls
Fix handling of backlight priorities.
Add the -b option to csd-backlight-helper

To allow csd-power-manager to communicate GSettings to
csd-backlight-helper, the '-b' option has been added. This is populated
with the search order of backlight handlers from the user on the command
line when it is invoked since pkexec doesn't preserve an environment for
GSettings when invoked by CSD.
