core: use new key name in command `/key` and configuration file

Legacy keys are automatically converted to new names when loading configuration
file `weechat.conf`.

Examples:

  "ctrl-I" => "tab"
  "meta2-1;3A" => "meta-up"
  "meta2-Z" => "shift-tab"
  "meta-wmeta-meta2-A" => "meta-w,meta-up"
  "ctrl-Cb" => "ctrl-c,b"
