Adds a bubble that asks a user whether to integrate the Spelling service.

This change implements the final UI that integrates the Spelling service into Chrome on Windows to measure actual QPS to the spelling service with Windows Chrome. This UI updatee consists of three parts:
* Add a context-menu item "Ask Google for spelling suggestions";
* Show a bubble when a user chosses the item, and;
* Hide the suggestions from the Spelling service if it is in the suggestion list of the local spellchecker.
