- Fix issue in handling SIGTERM/SIGINT that cause pgbadger to continue.
- Add autoclean feature to pgbadger in incremental mode. pgbadger will now removed automatically obsolete binary files unless you specify --noclean at command line. Take care that the old behaviour was to keep those unecessary binary files, now they will be removed if there's already a report in the day directory. In incremental mode (-I) only the binary files of the current parsed week are needed. This may help saving disk space.
