feat(/add): time parsing, link uniqueness, admin-only

- Add time parsing (HH:MM format) after date
  Example: /add Fix bug https://github.com/foo/bar april 15 14:30
- Update check_link_unique to return conflicting bounty ID
- Add_bounty now includes bounty ID in duplicate link error
- cmd_add now catches PermissionError and displays admin-only message
- Update usage text and help message
- Fixes #45
