Copied from IBL

Copied (with history) the common code from IBL. 
Removed Spring Configuration classes.
Builds on hudson https://ci-app.int.bbc.co.uk/hudson/job/iplayer-java-lib-common/3/console
Renamed packages from bbc.iplayer.ibl to uk.co.bbc.iplayer
Next step is to integrate into IBL and pull stuff from nitro2client
