Revert "drop twitter handle suffix for #115"
This reverts commit e50d4871.
Notes:
- Fixes #34.
- Related to https://github.com/FedStoa/moa/issues/115, in which the suffix was dropped apparently for aesthetic reasons only. Toots can sometimes look a bit noisy with the suffix, but I prefer the clarity of the handles referring to Twitter.
- Completely untested.
- Could be added as an option to the service in the future?
