v6.0.0-beta.0

This is a major release of the Unity Cache Server re-built from the ground up for better performance, stability, and maintainability. New features in this release:

• Modular cache architecture: the Cache Server now supports two different caching mechanisms - the default file system backed cache, and a fully in-memory RAM cache. Additionally, the system is easy to extend with custom implementations if desired.
• Transaction mirroring: file uploads can be relayed to one or more remote cache servers. This can be used, for instance, to mirror transactions from a local (in-office) development team cache server to a remote cache server used by external contractors.
• Unity project import: seed a cache server from an existing Unity project that already has a fully imported Library folder.

Instructions for basic usage as well as all new feature usage are documented in the README file.
