Minor improvements

Added a progress bar and a few other small changes, nothing major over 0.2.6, however the cumulative changes from 0.2.0 and additional testing that took place warranted the version bump.

No major new features and changes are planned, as the priority was to keep this simple for quick, local tasks. The intended use case was for syncing directories between local drives, while using syncthing for remote drives.

Updates will be less frequent going forward, with the main priority being bug fixes should any be found.
