responsiveness of tags in sidebar on edit tags page

[Robert Jäschke]

On http://www.bibsonomy.org/editTags the tags in the sidebar exhibit different behaviour depending on whether

1. I click on a concept/subconcept (nothing happens)
2. I click on a tag (I am redirected to the tag page)

In the old layout, one was able to click on the tags/concepts and thereby fill the field which had the current focus. This is no longer possible. I would suggest to restore this behaviour. (As a hotfix alternative, I would suggest to at least let the concepts behave in the same way as the tags.)
