Preliminary cut/copy/paste

[Ralf Engels]

Hi,
this is the first shot at cut/copy/paste for the developer  version.
One Problem I noticed: You copy a list of objects but neighter the clipboard 
nor other functions are able to handle list of objects gracefully.

Anyway, here is the patch.

By the way. Are you all on holliday?
