Additional statistics/client settings

Hi,

As a chorus director/band leader/tech person for a larger group I would like to be able to see the settings of each client. This would make it easier to get a more uniform sound or to help less tech-savvy users.

While it would be possible to have this in the server, a lot of servers run in headless mode. So I would prefer to have it in the client.

I see two options:
1. An additional dialog for this. In addition to the settings per client this dialog could also include statistics, e.g., server version, session length, number of dropouts, recording on/off etc. This option would have the benefit to see all clients in one page so that it is easier to identify outliers.
2. The information is added to the tooltip (currently Musician Profile) per client. At the moment, the tooltip wastes a lot of space by have everything vertically spaced. If the tooltip were to be expanded horizontally, a lot more information would fit in.

I would like to see the following information:
- Client Jamulus version
- Audio channels (mono/stereo)
- Audio quality
- Overall delay
- Reverb
