Import lxde-common.
I started packaged LXDE months ago, but not completed. 

lxde-common package provides a set of default configuration for LXDE.

lxde-settings is the XSettings daemon of LXDE.
It read config file ~/.config/lxde/config or /usr/share/lxde/config if
user-specific config file is not available, and presents the config values
to other programs via XSETTINGS protocol defined by freedesktop.org.
