Please consider adding OSGI metadata

[MarceloRuiz]

Hi Andres, I've been hitting my head against the wall for a day now trying to use ikonli in an OSGi project. Even after creating a bundle and reexporting all the packages the application cannot find org.kordamp.ikonli.javafx.FontIcon Would it be possible to include the OSGi metadata in future releases so the library can work seamlessly on OSGi projects too? Thanks! Marcelo.
