[svn] * docs/noffle.1,src/configure.h,src/configfile.c,src/noffle.c: Add optional "auth" parameter to '--server' option. This turns on client authorisation regardless of the setting of authenticate-client. Useful if you want the same Noffle to authenticate or not depending on what/how it gets invoked.
