did this originally, totally stupid. Anyway, the version number is now
a path argument to the script. No path info means version 1.0. In
other words, a URL like:

	/protogeni/xmlrpc/cm
	/protogeni/xmlrpc/cm/1.0

means to use version 1 of the API, while:

	/protogeni/xmlrpc/cm/2.0

gets you version 2 of the API.
