Clean Log Warnings, Enhance Runnability (#25)

* Only check the variable if it is set, avoid a log error.

* Pipe errors to SDOUT in case that's why Docker is not showing NPM progress.

* Two messages seemed very similar. Differentiate them.

* Check and install each dependency separately in case a lighter version is already installed.

* Don't require sudo if running as root.

* Use node instead of relying on shebang.

* Allow doing "npm start".

* Remove redirects, did not help see progress.

* Add a note when sudo is used.

* Fix node interpretor location to be arbitrary.

* Woops, need to keep advisories if the value is not set to false.

* Remove warning about apt CLI. Allow npm start to do dependencies.

* `npm start` is not magic, still need to run the install.

* Have `npm start` execute the main run script rather than bypassing dependency checks.

* Use PHP-CLI, smaller install size and more appropriate since only running local scripts.
