Figure out what to do with showing help

[alexander-myltsev]

We figured out what’s wrong with gnparser launch script. sbt-native-packager team just changed the environment, so our bash template stopped working. I would add tests to CircleCI to prevent it in future.

The reason we established custom gnparser template is custom help messages. Java launcher script uses -h | -help to show bash-specific help. scopt/twitter finagle uses --help. Consider sbt/sbt-native-packager#831. We need to discuss the way to combine them to drop that bash template.

A way we can solve it is to show help when no args are given. currently we launch web-server by default. but since native-packager generates web-serverscript for Play servers, I think we could give it a try.

We need to figure out how to merge those two helps.
