display custom label paths as tree

[TrimmingFool]

Inspired by the old lbll-suite plugin I came up with a tree display for the custom label paths:

I also added an option to show empty labels along the path to display the complete tree:

The shortened labels are also displayed for Labels > in the context menu:

...
Books
│Cat A
│Cat B
││Cat 1
││Cat 2
Image
...

label-size is not displayed if count == 0

Instead of spans I use a flex container with divs
to avoid the float: left of the tracklabel icons which conflicts with the label-prefix

updated all themes

Could the old view be toggled back?

P.S. I found it, it's the Settings, Format, unselect the "Show label path tree" checkbox.
