Support for Chrome Extensions

[cztomczak]

Upstream CEF supports Chrome Extensions APIs partially. Load chrome://extensions-support url in the browser to see which APIs are supported.

For this to be implemented we first need to expose Request Contexts APIs and that is to be done via Issue #244 ("Expose Request Contexts and Chromium Preferences").
