Back and Forward walk the panels too, not just the sheets

Opening a Properties or Link view was invisible to the history, so Back
from one did two things at once: it took the panel down and stepped to the
sheet before the one it was opened over. There was no way back to a
picture you had just been reading.

A history entry is now a (kind, element) pair naming what the editor pane
held -- a sheet, a Properties view, or a Link View -- and restoring one
puts that back: a sheet entry selects its tree node, a panel entry
re-opens the panel. So opening a panel is a move like opening a sheet.
Back from a Properties view lands on whatever came before it and Forward
brings the panel back, and following a link out of the Link View now has a
way home: Back returns to the picture the link was followed from, and a
second Back to the sheet that was open before that.

The panel's own Close is deliberately not recorded. It means "leave this
view", and recording it would put a sheet entry after the panel's, so Back
would re-open the panel that had just been closed. Leaving the position
alone means Back steps to what came before the panel and Forward re-opens
it, which is what the arrows are for.

Both arrows still go through close_editor_panel first, so unsaved
Properties edits are asked about exactly as before and a refusal leaves
the view and the position where they were. Pruning now has two kinds of
entry to check -- a sheet needs a tree node, a panel needs its component
still in the document -- and collapses any pair it leaves naming the same
view, since a Back that visibly does nothing is worse than a shorter
trail.

sheet_history and its functions are renamed for what they now hold.
