Filter update, fixed bot stop, v0.4.0

- Fixed `asyncio.shield` not being awaited in `ClientManager.stop()` (that led to `next_batch` value not being saved and session not being closed properly)
- `BaseEventFilter` does not have any abstract methods anymore and can be used to use callback for any event
- `BaseEventFilter.__repr__` prints class name now
- `BaseEventFilter.__call__` returns True now
- Added `EventTypeFilter` which can be used to check if the event is an instance of some class
- Removed most room events
- Added `NewMessageFilter`, `EditedMessageFilter`, `RedactedMessageFilter`, `SenderIsFilter` and `SenderIsBotFilter`
- Removed `FormattedTextFilter`
- Text filters are derived from `NewMessageFilter` so they won't match edited messages anymore
