FIX: removed old tests and commented out files
FIX: PoolXMLCatalog.addFile usage
CHANGE: InputDataAgent treats only the right transformations

Until now, the InputDataAgent was treating ALL the transformations,
even those for which it makes no sense (Extendable ones). Now treat all
but the extendables. Also leave the possibility to set explicitly what
transformations to consider.
CHANGE: clear replica cache when flushing or setting a file in the
workdirectory
FIX: print only once the end of processing of a transformation!
CHANGE: TSAgent: Make some methods more public for easy overload

Needed when willing to do strange things with the input files: I want to
indicate in the LFN the starting event number (/vo/something/file:3445),
so I need to be able to change the getDataReplicas method as well as the
getDataReplicasRM (to strip the :XXX).
FIX: Too many public things now

As the replica cache things are very very private, it's hard to overload
the getDataReplicas. Will overload only the getDataReplicasRM that use
only semi private things
FIX: mend the 'method'

Fix the number of _
