Configure JReleaser for assembling and releasing

[aalmiray]

Native executables are now generated via JReleaser.

To give it a try locally

$ ./gradlew :pierrot:build
$ ./gradlew :jreleaserAssemble

Inspect current configuration

$ ./gradlew :jreleaserConfig --select-current-platform

Perform a release in dryrun mode

$ ./gradlew :jreleaserRelease --select-current-platform -Pjreleaser.dryrun=true

Inspect

• build/jreleaser/out.properties
• build/jreleaser/trace.log
• build/jreleaser/release/CHANGELOG.md

I've tried locally and so far so good :-)
