Dave Miller 0c5f279c9d Standardize Error objects for Promises
Summary:
public

Promises are coming.  And as part of it, we are standardizing the error objects that will be returned.  This puts the code in place on the Android side to always send the proper error format.

It will be an error object like this
  {
    code : "E_SOME_ERROR_CODE_DEFINED_BY_MODULE", // Meant to be machine parseable
    message : "Human readable message",
    nativeError : {} // Some representation of the underlying error (Exception or NSError) , still figuring out exactly, but hopefully something with stack info
  }
