Dynamic Variables and Improved Benchmark files

[JacobMGEvans]

• Modified the make file to specifically execute sh on the run file which is set to be a bash file ecosystem.
• Set the environments in the bash run file utilizing a .env file for PORT, however, a fallback PORT can also be added. (waiting on an opinion if not necessary then-current configurations, meaning .env file needed for benchmarking should be added to documentation)
• based on @niftylettuce suggestion used the ladjs/env for the server.js file to be able to use both the .env and the bash file exported variables to local environment.

resolves #56

I created an issue for the breaking build. I noticed Travis was checking support for very old versions of Node which was failing on the test dependency Chokidar (they are using async/await) which is supported in a late version of Node 7 and after.
