Songrequests

[Laraakaa]

Add a generic songrequests-plugin.

The plugin should be able to allow requests across the following platforms:

• YouTube
• Spotify

The user should be able to select which platforms he wants to use.

To use spotify he needs to connect his spotify account to twasi. This should be in a seperate Twasi plugin.

Make sure that the API is available to make it accessible from the panel. We need to work with websockets to allow viewers to listen directly to the music. The websocket server should be suited in the songrequests plugin.
