Checking in the initial version of CEEE (Chrome Extensions Execution

Environment), an optional feature of Chrome Frame that acts as an
adapter layer for a subset of the Chrome Extension APIs. This enables
extensions that stick to the supported subset of APIs to work in the
context of Chrome Frame with minimal or sometimes no changes.

See http://www.chromium.org/developers/design-documents/ceee for an
overview of the design of CEEE.

TEST=unit tests (run ceee/smoke_tests.bat as an administrator on Windows)
BUG=none
