Don't focus new chat rooms / Don't steal input line when opening a new chat room

[Bart]

When opening a channel in a new tab, no matter you are typing or not, the new channel takes the input field and typing continues for the new channel. Really annoying.
Either add an option to open tabs in background, or detect when the user is typing, then open in background.

Should I add that this is a serious issue only when connecting to multiple server. When connecting to only one, all channels are there about the same time, but multiple servers can get connected with seconds or even minutes between same, that makes it unpredictable when the window will jump to another channel.
