easy fix: version.properties clash in multi-JAR classpath

The string VERSION is not inited correctly (runtime exception) in a multi-JAR classpath (i.e. when another jar with "version.properties").

**Interpeter.java**, line **117**: change to

       ` ResourceBundle b = ResourceBundle.getBundle("version",java.util.Locale.ROOT,Interpreter.class.getClassLoader());`

This will load "version.properties" locally from the bsh jar.

Cheers!

Mik
