**Bug Fixes**
- Address issue 23 by ensuring the same URI is not processed multiple times during the clean process (caused by trailing slash not common to all repositories from the Configuration file).
- Ensure download URL is formatted using forward slashes
- Ensure download command only adds custom arguments if provided
**Optimisations**
- Only attempt to download non-latest files, rather than all of them (saves Wget the trouble of checking the files)
