Unneeded System Tools menu

[Milan]

In Hardy, all applications that don't really manage system-wide or user
settings were moved from System->Preferences and ->Administration to
Applications->System Tools.

This is a good idea as a general rule since previously both
configuration menus were bloated by numerous tools. But in the default
install, adding a System Tools menu in Applications in not
user-friendly. The two only tools that appear there are hwtest-gtk and
gnome-system-monitor: these are not likely to be used by the base user;
furthermore, their use is very different from that of most applications,
i.e. editing documents, and so on.

So I suggest we choose either to put g-s-m and back to
System->Administration, or we hide its icon, adding elsewhere a way to
start it (a keyboard shortcut?), and the sme for hwtest-gtk. We may
consider short-term and long-term solutions to this, because the current
situation is IMHO not very good.

This was already raised in this bug (with one duplicate):
