[CB-4905] CordovaJS on Windows8 has memoryleak on exec.js
Created common exec proxy module

Since windows8 and firefox both used the exact same module
(commandProxy) I refactored this to a common/exec/proxy module.

I left the original commandProxy modules in for old plugin support
but will now log to the console to point to the new module.
Set VERSION to 3.3.0-dev (via coho)
