[GTK3] Migrate to AppIndicator3

Replace the old appindicator imports with AppIndicator3.

- Only few changes required due to Enum renaming.
- Updated the preference import to include require_version and set a bool.
- The password preference needs to be encoded for hashlib on Python3 but
also need to keep Python 2 support so attempt decode then encode.
