Add ts5

Will be added:
1.General volume on the server, as in ts3 on top of the sidebar.
2. General button to subscribe and unsubscribe from channels.
3. At the moment there is no choice of localization, but localizations are present in the folder with ts5


The subscribe button was confusing to many people so I would not count on it to come back.

  1. Clear channel history.
  2. General volume of the volume on the taskbar.
  3. What the person is playing at the moment (for example, like in Discord)
