* Minor performance improvements:
- Avoids updating font and color in TextBubble if it's not needed: would make attributed text to update
- Avoids updating views in selected setter if value didn't change (setter is called by the collection view as part of dequeuing)
- Avoids creating dictionary of attributes all the time for date attributed string (for some reason this was appearing in profiling with some swift-to-objc conversions)
Uses enum as image key in text style for greater safety.
* Removes linter warnings
