Simple OAuth1 implementation based on http://code.google.com/chrome/extensions/tut_oauth.html.

Simple OAuth1 implementation based on http://code.google.com/chrome/extensions/tut_oauth.html.

This copies the files from the extensions example.  We're okay with this fork as we will replace this with an OAuth2 handler once the server side is setup correctly.

BUG=none
TEST=manually step through getting/clearing token.

This should give you OAuth1 tokens + a class which actually signs your requests
for you.  You should be able to use this to talk to Googleapis.com using either

  chromoting.oauth.sendSignedRequest()

or composing things by hand with the result of 

   chromoting.oauth.getAuthorizationHeader()

I think this line might be a tad over the 80-character limit ;)

That's OK as long as it makes the code more readable. ^_^
