Revision 2278

adjust excluding GNOME settings from menus

GNOME settings tools were excluded from several menus because
- GNOME has its own menu for them
- They are not relevant for non-GNOME

However, GNOME doesn't seem to have a separate menu for them anymore,
but instead has a control center.

Also, they matched some applications that are useful in non-GNOME (like
GParted).

Therefore, exclude only entries that have
- X-GNOME-Settings-Panel (they are included in GNOME control center)
or
- GNOME and X-GNOME-*Settings (they seem to be individual application
  settings shortcuts, useful mostly in the previous distinct settings
  menu but not so much cluttering the general Tools menu)

This shouldn't hide any previously visible tools, but should fix e.g.
missing gconf-editor.

This also has the effect that GNOME;HardwareSettings; tools like GParted
now appear in KDE under SystemTools.

If unwanted applications appear, they should get OnlyShowIn/NotShowIn,
get moved elsewhere, or handled individually in some other way.
