[.rtorrent.rc] Remove vim metadata from the bottom, we have ftdetect for it
[.gitconfig] Add user.signingkey as it is not automatically detecting it
[.gnupg/gpg.conf] Remove exec bit, doesn't seem to be needed
[.ssh/authorized_keys] Add virtuoso's key and new rakim's key
[.xinitrc .xxkbrc] Add czech language layout in alt group of xxkb

This means that when pressing lalt, xxkb will toggle between en/gr only, and I
need to right-click xxkb's icon in system tray to toggle between en/cz layouts
