Ship kscript as one semi-binary file

[dmitry-novikov]

First of all — it works!
It's possible to ship kscript as one file with both shell script and jar files inside. To do so, just cat kscript.jar into slightly modified kscript shell script. This is how united file may looks like:

#!/usr/bin/env bash

# version tag for backward compatibility with kscript v1.x
KSCRIPT_VERSION=2.0.0

exec $(kotlin -classpath $(dirname $0)/kscript kscript.app.KscriptKt "$@")
exit

<BINARY CONTENT OF JAR FILE>

It's known feature of tar/unzip to skip any content until their own header.
I've tested this hack on java versions "1.8.0_144" / "9" and it works. With java 9 I still faced issue #41 but I think it's a different story.

In know it works see https://github.com/holgerbrandl/kscript/blob/master/misc/experimental/jar_embedding.sh

However, the script with binary payload failed to work (at least for me) when using cygwin, that's why I dropped the idea for now. Also from a user perspective we don't gain much by doing so.

Sad that it doesn't work on cygwin.
