[0.7.2] Fixes for pre-Node 4
This release mainly fixes issues with older Node platforms (v0.12 and v0.10). We do recommend using the most recent LTS version of Node (v4), however.
Changelog
- Improve callback handling for send and register
- deps: move jest to optional
- Fix object check to work in older Node
- resources: Use more for loops over foreach (performance)
- resources: Turn DataStore into a 'named' type to make instanceof work.
