Improvements of Trashcan

[Martin Svensson]

Here follows a suggestion of trashcan improvements:

• Change the name of button 'Delete' to eg. 'Remove' to avoid confusion with the rest of the 'Delete' buttons.
  
• Add a 'Delete' button on the trashcan-viewpage when an item is restored. The function should be to set the remove flag again.
  
• Make it possible to follow the dependencies to items that are using the current item. In other word: the icon in Trashcan listpage should also be visible in the list of 'Items using...' on Trashcan viewpage.

Relates to ticket:252 and ticket:576

Milestone BASE 2.4 deleted

Child bioassaysets/transformation is not restored when restoring a transformation/bioassayset in trashcan

[Martin Svensson]

(In [3549]) References #611. Added new icon and text on the delete button in trashcan-listpage. Added item-is-used-icon for those child items which are deleted but not possible to delete from trashcan.

[Martin Svensson]

A restored item should not be possible to view in the trashcan, while it's not in the trashcan anymore. Therefore should the second item be replaced with following
*When an item is restored from the view_item page, the browser should be redirected to the item's own view page.

(In [3550]) Fixes #611 Improvements of Trashcan. Changed confusing button text/icon. Browser is now redirected to an item's view page when the item has been restored from trashcan->view_item.jsp
