    location-entry: Encode URI before copy/paste
    
    The location entry is currently the only place in our UI where it is
    possible to copy a decoded URI. This is basically never what the user
    wants.
    
    I am getting tired of accidentally pasting broken URIs like
    https://build.webkit.org/results/GTK Linux 64-bit Release
    (Tests)/r196216 (13627)/results.html. URIs should be encoded before
    stored in the clipboard. Now I can copy
    https://build.webkit.org/results/GTK%20Linux%2064-bit%20Release%20(Tests)/r196216%20(13627)/results.html
    instead as nature intended.
    
    Of course, if only part of the entry is selected, then it's not a full
    URI and should not be messed with; in this case, just copy it raw.
