[request] audio playback, favorite list, minor improvments

[makedir]

Really like the app but it would be great if you could implement and change the following:

Add:

• audio support, with audio playback in the background + chat disconnect when app is in the background
• favorite list, add a simple list where you can add channel names to it, to easily access them
• option to disconnect and close chat

Improvments:

• make it so that tapping on the video reduces the chat frame size again into the small version (I tapped on the pen icon on the chat bar, and now the chat is always in enlarged mode, taking away 50% of the screen, not sure if this is a bug, but there is no way it seems to reduce the chat into smaller version, like 20% of screen instead of 50%)

• remove the gray line seperating video and chat

• blend out buttons after a few seconds
