org.jmacs 1.16

• ~.pd.IDevice.IStatus, IDevice.IConstants added: this is to promote robustness (by avoiding having too many arguments of type Object about the place), at the expense of a little extra work on the part of the programmable-device developer
• ~.pd.IInterpreter.interpretCmd: status and constants args no longer of type Object
• ~.pd.IPdCmd.execute: ditto
• ~.pd.IProgram.init, wake, terminate: ditto
• ~.pd.IDevice.IStatus.IFactory replaces IDevice.IStatusFactory: deemed to be a bit neater (now that we have an IDevice.IStatus); getStatus() now returns IDevice.IStatus rather than Serializable

• ~.IDiDriver.IClient: setContext(IDiDriver.IContext) added, so that this interface can be implemented where only the status of another DI will be requested
• ~.pd.DiClient: all constructors now throw IllegalArgumentException rather than MalformedURLException if devicePkgname malformed; javadoc updated
• ~.pd.DiDriver: requires further scrutiny!
