Prefer binary stylesheets

Compile our JavaFX themes into .bss files, which should load slightly faster.

@overheadhunter Is there some sort of official documentation for this feature? I only found old posts about an javafxpackager.

[overheadhunter]

Only in JavaDoc. The css2bin flag from javafxpackager has been dropped in jpackage, as "JavaFX-specific features" are declared non-goals in JEP 392.

JavaDoc suffices me! Even thou the used Css2Bin class has no documentation, it just calls Stylesheet.convertToBinary(...).
