This patch is used to add support for syslog messaging implemented in WINGs lib directly, so available from the lib itself and wmaker too. I believe it will in a first time help to get some logging info centralized in one point, and in a second time maybe add some info level messages like wmaker is starting, stopping, restarting and else. For now, it's built by default when the syslog support is found, maybe we could also disable it by default.
