Sway cannot parse config option floating_modifier.
It appears that this config option has existed before, and is currently
waiting to be reimplemented.
In the meantime commment the config option, so that the user does not
get confused if the config parsing gets halted half-way though or not.
Swayidle handles idle events and allows
for dpms and lockscreen handling. It also
handles systemd sleep events, and can
raise a lockscreen on sleep
Fixes#541
Exherbo installs architecture dependent data in a different place than architecture
independent data. More concretely: binaries go in /usr/$chost/{bin,lib},
data goes in /usr/share and configs in /etc, /etc is already configurable
through CMAKE_INSTALL_FULL_SYSCONFDIR but the datadir was not. This
patch fixes it so that things can be pushed in the right places.
