v2.0.0 (Deployable with TLS/SSL + Docker)

The previous version v1.0.1 was not able to deployable on the server with TLS/SSL security encapsulation, but now it supports and (somehow) stabilized.

It's not that all issues and improvement suggestions described in #1 are all resolved in this release, but the deployment stabilization has been proved after experiencing lots of trials and errors.

Installation and server deployment configurations are described in readme.MD in this repository.
