Add applications-defaults

The file /usr/share/applications/defaults.list enumerated the defaults
applications to open files of specific mime types. If this file does not
exist, the default is more or less randomly selected from the
applications available for a specific mime type (as defined by
/usr/share/applications/*.desktop).

The default settings can be overwritten by an individual user by the
"MIME Type Editor" xfce4-mime-settings).

This information is used by exo-open, which itself is called by xdg-open
if an Xfce desktop is detected.

Import existing file into repository.
