Sackmesser - Developer Email Address - Casing

[billabongrob]

The sackmesser tool is capable of performing edge exports that can be used to import into Apigee X. When using the exported content, one error that we ran into when executing and import was POST https://apigee.googleapis.com/v1/organizations//developers

{
  "error": {
    "code": 400,
    "message": "email address has to be lowercase",
    "status": "INVALID_ARGUMENT"
  }
}

Would it make sense to either add a flag for the type of env it's planned to be imported to or similar, in order to trigger a thing (sed, etc..) to clean this up?
