Support for platform dependent and native libs

[tschulte]

I am not sure if gradle does have support for this, but this plugin should allow defining native dependencies and create corresponding entries in the jnlp.

Workaround until this feature is ready:

configurations {
    jnlpWithoutNatives { // <1>
        extendsFrom jnlp
        exclude module: 'jdic-native'
        exclude module: 'jdic-stub'
    }
}
jnlp {
    withXml {
        resources("os": "Windows") { // <2>
            project.configurations.runtime.findAll { it.name =~ /-stub-.*-windows/ }.each { jarFile ->
                jar tasks.generateJnlp.jarParams(jarFile)
            }
        }
        resources("os": "Windows", arch: "x86") {
            project.configurations.runtime.findAll { it.name =~ /-native-.*-win32/ }.each { jarFile ->
                nativelib tasks.generateJnlp.jarParams(jarFile)
            }
        }
        tasks.generateJnlp.from = configurations.jnlpWithoutNatives // <3>
    }
}

1. add a new configuration that extendsFrom the default jnlp-configuration, but excludes the jars containing the native libs and stub-jars that differ from platform to platform
2. add platform dependent resources blocks to the jnlp file
3. before the jnlp-task adds the rest of the resources, change it's source to jnlpWithoutNatives

Another thing this might include: different library versions depending on java version. Example: ControlsFX needs different jars to be used depending on the Java version.
