I'm unsure about the first point. This will make the tabs distinguishable if
there are e.g. multiple tabs to different FTP servers (see bug report). But
the labels are also longer.
Please comment.
Changes to panel tab label
- added host if not empty
- special label on startup when dir does not exist
- fix crash when [panel not visible]+[non existing dir]+[show full path]
FIXED: [ 267756 ] Rename tab or add prefix to tab label
BUG: 267756
