Releasing new updated version 4.0
Primarily updates for BSON and YAML (Mongo has been deprecated in favor of MongoDB, and Symfony YAML 3+ handles exception throwing differently than 2.x), but also includes a fix for MSGPack error handling.
- Added support for MongoDB extension (while keeping support for Mongo extension)
- Fixed error detection for MSGPack
- Fixed error detection for YAML, including support for pre-3.1 and post-3.1 differences
- Minor cleanup
Relates to #31, Thanks to @danhunsaker
