Kinda runs, but functionality from the original main loop
is still missing. Patience.

This is a work-in-progress, code is currently broken.
(Some actions, and notably, the header, are missing.)

Made the logic more modular, hopefully easier to follow,
and removed repeated code.
Plus, some optimization in RichString code.

It is now accessible via F6 when on tree view (as a bonus, it is
now also reachable via the mouse). The function bar now dynamically
changes to reflect the toggle nature of the tree-view mode (F5)
and the F6 key serves as expand/collapse when on tree mode,
and its previous behavior of bringing up the "Sort By" menu
(which only made sense on non-tree mode). Users wishing to go to
the "Sort By" menu straight from Tree View can still do so with the
"<" and ">" keys (the top-compatible keys for sort selection).

plus some fixes

Reduces resulting code size.
