Remove unused excel files.
Merge pull request #690 from 4teamwork/deif-remove-xlsx-cruft

Remove unused excel files.
Revoke list folder contents permission for Administrators on repository.
Fixed test name in remover tests.
Add repository delete action and confirmation view.
Adjust global role mapping for delete objects permission.
Adjust `Delete objects` permission for repositories.

With the previous changes on the rolemap.xml the `Delete objects` permission
is not longer avaiable for Administrators. But the Administrator should be
allowed to remove repositoryfolders. Therefore we extend also control the
`Delete objects` Permission in the repository workflow.
Revoke delete permissions for dossiers

This is necessary because the repository workflow has changed so that the
Administrator role has newly the `Delete objects` permission.
Therefore aquiring the `Delete objects` permission is no longer possible.
Added monkeypatch for _verifyObjectPaste to allow moving content without delete objects permission.
Update `opengever.repository` translations files and add german translations.
Added `removed` method to document and mail builder.
Extend body class for removed documents or mails.

This allow us to display specific icons and wartermarks for removed objects.
Prefix links of removed documents with an additional removed span.

This allow us to display and additional icon in front of the regualar
icon for all removed documents in the trash listing.

An global implementation, which would work for all document_listings is not
necessary, because all removed document has to be trashed before.
