Adopt standard Ctrl+Q key combination over current Alt+X

[macho]

To conform to standard Ubuntu practice, I believe that the Torrent >> Exit menu item should be associated with the Ctrl+Q key combination rather than Alt+X, as it is currently. The vast majority of Ubuntu apps associate “Quit” with Ctrl+Q, but even those that instead include an “Exit” option (e.g. LibreOffice) still associate that option with Ctrl+Q.

Ideally “Exit” would be renamed to “Quit” for consistency, but even failing that change, I believe that Ctrl+Q should be preferred over the idiosyncratic Alt+X.

Thank you!
