mumble server connect dialogue has two nmemonics for "C"

[Muelli]

When starting mumble, the server connect dialogue appears. In the bottom row are four buttons, Add New, Edit, Cancel, Connect. The former two share the same mnemonic: "C".

I have expected separate mnemonics to be given, so that I can press Alt+C to connect (or to cancel).
