Create new user with copied settings from another user

[Nicklas Nordborg]

When creating a new user it would be useful to be able to create it with the same settings (group/role membership, quota, etc.) as another user. Personal information should of course not be copied.

Adding a 'copy' icon on each row in the table list and a 'copy' button on the single-item page could be the starting point. The regular new user dialog could then be used and modified to bring in the information from the selected user.

(In [6383]) References #1733: Tag items should be annotatable

Fixes the Extract.getAnnotatableParents() method so that it calls the super-class method and only add the Tag if one is present.

Removed the Extract.getParents() method since it doesn't do what it says (it only works if the extract has a single extract as parent). If the parents is a sample or multiple extracts the query return nothing.
