Add authentication support in hudson.Main (if username/password are included in

HUDSON_HOME URL, then include Authorization header in Hudson http requests).

Also moved Functions.isUnitTest to Main.isUnitTest, to remove dependency on
winstone.jar for running hudson.Main (Main uses EnvVars which checks isUnitTest
flag.. in Functions which uses servlet classes).

Updated http://wiki.hudson-ci.org/display/HUDSON/Monitoring+external+jobs
with info about required jars and authentication.
