function-eslint doesn't know about Buffer, util and modules imported in functionExternalModules

[pauldeng]

Current Behavior

Similar to issue #22.

The function-eslint rule complains if a function node references Buffer, util and modules imported in functionExternalModules - saying they are not defined.

Expected Behavior

Any built-in object the Function node provides should not cause lint errors.

Modules added to the Setup page of function should not cause lint errors.

Steps To Reproduce
