    Add supported mime types to .desktop-file
    
    Mime types supported by seahorse should be announced in
    /usr/share/applications.
    
    I got the mime types supported by using the following command:
    
    for mime_type in $(grep -F add_mime_type src/key-manager.vala |cut -d\" -f2); do echo -n $mime_type\; 
;done;echo
