feat: display quickemu console output

[seltzered]

Thanks for making this! Just starting to play with this but feels more intuitive than virt manager for basic needs.

I feel like when launching a VM one of the things many users may be searching for is connection info. while there's currently info for ssh, there's not other info that gets outputted by quickemu upon launch - such as SMB connection info. Perhaps the raw output from quickemu could be shown in quickgui?

As with the SPICE and SSH ports, I think the best approach for this is for quickgui to discover the relevant bits of connection info for each VM and display them, rather than exposing the console output to the user. If possible, it should also provide a button for connecting with the appropriate app.

@marxjohnson I could have quickemu drop a json file (or something) in the VM directory that Quickgui can consume?
