Fixes for KAS

After some testing I can't find any more serious issues myself, so submitting the request.

Has some things that can be called minor features:

* When attaching parts, it is now possible to rotate them around two other axes by using Left Alt and Right Alt with the usual keys.
* Containers can be configured to store the full state for certain part types, which is necessary to prevent a way to cheat with resources etc.
* Added the static ladder and the new stock antenna to the config.
