appJar variable is not expanded correctly.

I am using 1.0.0

When I inspect the izpack.xml I see the appJar variable expanded incorrectly:

<variable name="appJar" value="C:\scm\incubator\scala-daemon-example\target\scala-2.11\scaladaemonexample_2.11.5-sbt.SettingKey$$anon$4@4cbfa888.jar"/>

It looks like the version property is being incorrectly substituted with the property name itself instead of name.value.

Indeed this looks to be the case in Izpack.scala:

val jarName = "%s_%s-%s.jar" format (normalizedName.value,
                                       scalaVersion.value,
                                       version)
val appJar = FileUtil.joinPath(classesParent, jarName)
