Subject: [PATCH] Show the implied price on every ledger line, not just the
 totals

Price was blanked on the bridge lines and on the excluded row, so a ledger
that had both measures on every line showed a price on two of them. Baseline
sat there as 2,242,180.67 over 8,111,717.10 with the column empty.

A bridge line's price is the implied price of that initiative's own
contribution -- Scale #116 above works out to 0.2397 against a current
0.2735 -- which is the number that says whether the initiative was a price
move or a volume move. That is the same question the plug toggle asks about
the edit, answered for the adjustments already made.

A line with no units is left blank, since its price is undefined rather
than zero -- the "price" bridge line in that example moved dollars alone.

The price column's hint said "holds units", which stopped being true when
plug arrived: it holds units under plug = price and moves them under plug =
volume. It now just says what the column is.
