+Makes possible downloading and installing signed resource files from a server.
+You must subclass it and implement the @ref installResource() pure
+virtual method to install a resource. For uploading you must create a resource
+tarball (which is installabale by @ref installResource()) and call the 
+@ref uploadResource() method with this tarball as the argument.
+Signing and verification is done by the gpg application, so the user must
+have it installed, otherwise this class does not give any extra security compared
+to the standard KNewStuff class.
