Add startup errors, mention XDG_RUNTIME_DIR in README

Browse source 
It was just exiting with code 1 for me. The problem turned out to be
that you *need* to set XDG_RUNTIME_DIR or it won't work (I think e.g.
systemd does that for you, but on Void it's not set by default), so
mention that in the README.

This makes it ideal not only for initialization but also for execing into a
user-level service manager like s6 or `systemd --user`.
You'll have to explicitly set `XDG_RUNTIME_DIR` if your system doesn't do it for
you, e.g. `export XDG_RUNTIME_DIR=/tmp/xdg-runtime-$USER && mkdir -p
$XDG_RUNTIME_DIR`.
More/less verbose output can be requested with flags as well:
* `-q`: quiet (log level WLR_SILENT)
