Support for "-Xset:name=value,name=value,name=value". The name/value data is stored in a properties object in the world and is accessible through getExtraConfiguration(). This will enable easier tailoring of weaver/world behaviour since you wont need to add new X option processing for every little thing. Should possibly only be used for tuning parameters.
