Support for using two cores at once
In my day-to-day work, I need to be connected to both Freenode, and an internal IRC network only available over a VPN. It's not possible for me to run a core that can handle both (if the core is outside the VPN, it can't connect to internal IRC; if the core is inside the VPN, I can't connect to it from, say, my phone or cafe wifi easily).
It would be great if the Quassel client supported two connections at once, so I could run a core on the public internet for Freenode, and a second core inside the VPN for when I'm working. In my use case, there's no channel or network overlap, just for clarity.
