[Large; Chromium OS] Work to host the cloud print dialog when built

for Chromium OS.  Currently disabled by default behind a command line
switch, and containing a non-real URL for now, this code is at
prototype level.  It works (when enabled and pointed at a functioning
cloud print service URL), has the beginnings of some unit tests, and
has the beginnings of deeper communication with the dialog contents,
and it shuts off the DOM UI access from the dialog contents.
