Google BrowserChannel server for NodeJS

# I require a local version of the closure library because the version in google's
# REST service is too old and crufty to be useful.
#
# You can get the closure library like this:
#
#     % svn co http://closure-library.googlecode.com/svn/trunk closure-library
#
# And download the closure compiler JAR here:
#
# http://code.google.com/p/closure-compiler/downloads/list
#
# I also compile with this patch to the closure library:
# http://code.google.com/p/closure-library/issues/detail?id=388&sort=-id
# ... which fixes a couple timing issues in nodejs.
