gui: the path keeps its telling end, and the checklist grows three items

Squeezed, the toolbar's path label read "/t... ds". It now elides the
start, since the end of a path is the part that says which directory
this is, and will not shrink below about sixteen characters; the
tooltip still holds it in full.

The checklist gains the reordered bar, the About block, and the
sandbox trap that had every file skipped: krino's own (min-age 2m)
ignores a file written in the last two minutes.
