* added built-with-matrix-nio badge to README
* permit aliases
- using room.is_group is not ideal to determine if a room is a DM
- if a room alias is created for a DM, the existing code will break
- changing to check for room.member_count seems to be more appropriate
- new code also works on DMs that have aliases
* moving badge next to existing badge
* Update my_project_name/callbacks.py
