Build in commonjs_strict mode

[ChALkeR]

package statements removed from protocols, since in strict mode the whole namespace is exported instead of the package, and keeping the packages would have required changes in all js files that import protocols.

Had to rename one ConsensusService -> MirrorConsensusService, as there were two different entities named ConsensusService.

This mostly solves #267, apart from #268. I.e. with this patch, the only thing that remains polluting the global scope is:

> proto
{
  google: {
    protobuf: {
      BoolValue: [Function],
      BytesValue: [Function],
      DoubleValue: [Function],
      FloatValue: [Function],
      Int32Value: [Function],
      Int64Value: [Function],
      StringValue: [Function],
      UInt32Value: [Function],
      UInt64Value: [Function]
    }
  }
}

which comes fromgoogle/protobuf/wrappers.proto (see #268).

Thanks for the change here. I completely agree that commonjs_strict is the right way to do this. I was unaware it existed myself.

Interestingly enough, this did break everything.

Hm. This is interesting, as this was loaded correctly and test:unit passed. I'll check what's going on there.
