FX API docs bundle has a broken link to dejavu.css

The javadoc tool now generates the following line in the stylesheet.css file:

@import url('resources/fonts/dejavu.css');

However, this file does not exist in the generated bundle so this results in a broken link. See RT-36288 for a description of the problem that this causes when deploying the JavaFX docs bundle on OTN.

We need to do two things:

1) Until this is fixed, we need to manually apply a patch to any JavaFX doc bundles to remove the import statement.

2) We need to fix the JavaFX docs build to include the dejavu.css file and related font files.
