Fix window title not filled by default

In the config, if `window` is undefined, the derived `Default` for the
String `title` is used, which is an empty String. This was unintended,
and causes issues in gnome-shell (e.g. in the alt-tab dialog) when the
window title is an empty string.

This commit adds a manually implemented default for the `WindowConfig`,
it's the same as the derived `Default`, except for the `title`, which
will now always be "Alacritty" as originally intended.
