Tag selection after tag deletion behaviour

[Ldp]

r2741 in response to #4261 changed the tag selection handling.

What happened before is that if you deleted a tag, the next selected tag would be the one that was now at the same position in the taglist as the deleted tag. You could easily delete tags 3,4,5 out of a list [1,2,3,4,5,6] in rapid succession, by selecting tag 3 and pressing delete three times.

What happens in 2741 is that the top tag is always selected after you delete a tag. Deleting tags 3,4,5 in the example now involves having to select the next tag to be deleted, each time.
