The Tags FIAP querys the tags ioslave for all known tags, which is filled by Baloo. This makes the FIAP useless without Baloo, so don't show it when baloo is disabled
I think we should step back and create Task for proper Tag handling:
- Removing a tag from the last file removes it from the tag list
- Creating a tag is only possible by assigning it to a file
- We have no tag attributes, e.g. color, custom emblem ...
- The FIAP is also shown for files on e.g. FAT, where XAttr and thus tags are not supported
