Improve music support
It would be great to improve support for music. This may allow more people to use Neochat as a default messenger. "Support for music" means:
- Allow music to be played in the background even if user srolls the list. Now it just stops.
- Playlist view which can be used to switch between the tracks. Maybe below the chat title and search field (like in Telegram and many other apps).
- Integrate with KDE to allow player control with KDE's tools.
- Support detecting type of file that may be used both for audio only and video+audio data with first bytes (for containers like .mp4)
- Allow to control the position of the track
- Show an error popup when the file cannot be played. Now it silently falls. This may help user to determine and fix the problem
