> This PR adds a "compile" process instruction to FXML files with the optional PI data "true" (default) and "false". The
> PI data is turned into a boolean value using "Boolean.parseBoolean(String)".
> This makes it possible to inject the compile PI everywhere in a FXML file and turn on and off compilation of scripts if
> the scripting engine implements the javax.script.Compilable interface. The PR adds the ability for a fallback in case
> compilation of scripts fails, in which case a warning gets issued about this fact and evaluation of the script will be
> done without compilation. Because of the fallback scripts get compiled with this version by default.
