The hotkeys were reworked for Alt+1..0 to switch between the channels specifically to the current server we're under and Alt+Shift+1..0 to switch between only the servers. This should make it easier and (in my opinion) more intuitive to handle connections to many channels at once over many networks, as tends to happen when you go through a bouncer, which are increasingly popular.

An issue was found throughout the process of adding this where Alt+1 and Alt+0 returned an "ambiguous shortcut" error message from Qt. I found out that the weird pattern of it only being Alt+1 and Alt+0 was pure coincidence. I am in two channels, one of which starts with a 0, the other with a 1. The shortcuts Alt+1 and Alt+0 were therefore given to them. I'll start working on this issue.

There was another potential issue that I haven't experienced where if a user would disconnect and close a server, then join another server, the server list wouldn't be updated because the size would still be the same. The hotkey would try to go to a non-existant ChatWindow* and lead to unexpected things. I decided to simply unconditionally update the server list on every call as a lazy workaround.

So as of right now, there should be no introduced bugs as a result of this patch.
