[whisker] Repackaging org.apache.rat.whisker -> org.apache.creadur.whisker ...?

[Robert Burrell Donkin]

ATM whisker is packaged in org.apache.rat.whisker

Given that our podling just awaits board approval before graduating into 
Apache Creadur TLP, it seems sensible to repackage the whisker code into 
org.apache.creadur before pushing 0.1

Opinions? Objections? Comments?
