As discussed here: http://nabble.documentfoundation.org/Libreoffice-ux-advise-Recent-files-dropdown-td4052945.html#a4052996

The changes are (inspired by Gedit):
* Display only the filename, not the (abbreviated) path
* Show the protocol name before the file, if not local (e.g. "ftp: myfile.odt")
* After the keyboard shortcut (a number from 1 to 10) display a '.' instead of a ':' (because the protocol has a ':')
* FIX: Display whitespace as whitespace, not "%20"
