Terminal: move "Window title..." from "Edit" to "Settings"

The menu item to set the "Window title..." makes more sense in the
"Settings" menu. There you find other settings that only apply to
the running session, like window size or text encoding.
The "Edit" menu OTOH has only commands to deal with the contents
in the Terminal, like copy, paste, find etc.
