[patch]: geyes property box behaviour fix

[Peter Hawkins <peterhawkins ozemail com au>]

Hi there...

This patch stops gnome-applets/geyes from opening multiple property
boxes, which the existing code allows. If you actually do open multiple
property boxes, screwy things happen like being unable to apply changes
in one of them, weird gtk/gnome warnings, etc...

=)
