restarting and daemonizing on unix. daemon sends log messages to syslog. unix now reads config file from file named on command line; if no command line arg then uses effective user's config file and if that's not there it finally tries /etc/synergy.conf. if there are no screens configured then one is added for the primary screen. broke some startup stuff on win32. also now timing out if X primary screen can't grab the mouse and keyboard. the server will just give up trying to switch screens. the grabs will fail is some other app has a grab and won't release it. note that kdm grabs the keyboard for the duration that the login window is displayed, effectively disabling synergy.
