Revert of [Courgette] Adding CourgetteConfig singleton and --experimental flag. (patchset #5 id:80001 of https://chromiumcodereview.appspot.com/1306193004/ )

Reason for revert:
The original CL assumes Courgette had to deal with forward/backward compatibility issues.
Turns out that (as seen in http://crbug.com/459505):
- Courgette executable is shipped with new releases.
- This allows Courgette workflow to proceed without being tied down to legacy.

These new (to huangs@) facts render the original CL redundant.
