Few improvements

• Radically improve speed of incremental backups (check recent snapshots first)
• Support for separate retention settings for external backups (to other partition/disk)

First formal release

There was 0.1 version, but that was just an experiment and it didn't make actually backups, just snapshots within the same filesystem, 0.5 does real backups now:

• Code moved into class
• Fix for Ubuntu 15.10 (binaries moved from /usr/sbin to /bin, now both cases are supported)
• Refactoring into multiple methods
• Fix for 0 as count of keeping snapshots
• Real backups to other partition/drive added, not just snapshots
• Some changes in output messages
• Custom path to config file can be specified as argument
