title: Cruise Control .NET not fails build when source control exception occurs
body: <p>Cruise Control .NET not fails build when source control exception occurs and this is very unexpected because shows build status succes in tray icon. I tried to use modificationDelaySeconds,maxSourceControlRetries,sourceControlErrorHandling, stopProjectOnReachingMaxSourceControlRetries blocks without any result. I tried also to check connection to svn server in prebuild and publisher block, but prebuild block it's excute after source control block so it never happen and publisher block cannot fail build... </p>
