Felger/AutoPruner — pull request #2 by pjf (2014-12-18 19:03:08+00:00)
Title: Pruner refactor and optimisation.

- We now *only* search directories that can contain files we might
prune. This is *much* faster, and means we don't go causing issues in
the ATM cache or elsewhere.
- Files and directories to work with are pre-calculated, paving the way
for a proper test suite, and giving the user feedback on how much work
will be performed.
- Better protection against variable leaks.
- Moar documentation.
- Passes `perlcritic --harsh`.
- FASA_Tanks: Removed duplicate rule
