0.8.0 Release

This 0.8 release of Trellis focused on performance enhancements, a consolidation of the internal Java APIs, and Docker deployment options. This will result in more options for persistence layers and deployment scenarios.

Some notable changes include:

1. JSON-LD serialization is now compact by default
2. Simplification of configuration files and support for ENV properties
3. More options for JWT authentication scenarios

Internally, the HTTP layer is now entirely asynchronous, which means Trellis will scale larger and run faster.
