Some possible menu improvements

Binary package hint: xubuntu-default-settings

Hi there,
This bug concerns Xubuntu 9.10 beta.

I noticed some menu entries that were not actually likely to ever be useful, and that thus could be easily hidden:

 * OpenJDK Java 6 Webstart which apparently only serves to manage the Java applets you allowed on your browser. I don't think it's that useful to expose this considering Java applets became so rare. I think users wouldn't modify this kind of settings without a doc, so the doc could just give the magical command to launch instead of that menu entry that spoils Apps->Internet.
The same applies to OpenJDK 6 Policy Tools in Apps->Settings.

 * Authorizations, in Apps->System, points to a PolicyKit management UI, that only allows changing the users' rights about PolicyKit itself. I think this app shouldn't be exposed to the GUI as long as it's not actually useful.

 * Do we really need Mass Rename to be available in the menu? I think users will only need it when they have several files selected and they want to rename them, and when they do it's being launched by thunar anyway.
