All communication with the cloud print proxy service from the browser now happens in the CloudPrintProxyService class. Added code to start the service process if the cloud print proxy was enabled. Also, when detect an auto-update, we send an IPC to the service process. The service process then shuts down when the browser disconnects.

BUG=None
TEST=Unit-tests, test Cloud Print proxy UI, test that when an update is available, the service process shuts down when the browser does.
