javafx-maven-plugin-8.6.0

After three months without a new release, it feels refreshing to have some minor tweaks for you folks. Now all my "open" issues are down to non-critical bugs, it is time to take care of the website, which is heavily outdated ... the polymer-project got some nice mayor upgrade, so this in mind the next goal is to make you happy again.

New:

• added new property useEnvironmentRelativeExecutables to make sure having the correct executables used, required when having multiple installations of java, just set this to false for using the JDK used for executing maven (this got migrated from the javafx-gradle-plugin)
• added new property runAppParameter for specifying application parameters passed to the execution call java -jar while developing your application (this fixes #176, because that issue got valid as the mvn jfx:run goal is valid again after the removal of the exec-maven-plugin)
• added new property runJavaParameter for having additional settings passed to the execution call used for running your javafx-application, makes it possible to specify javassist-parameters now (and much more)

Bugfixes:

• fixed tests not running on MacOSX due to different paths exceptations (thanks @sa-wilson)

Improvements:

• cleanup of some unused parameters
• fixed missing "s" inside description about jfx:list-bundlers-mojo
