Add new dynamic label variable $U.

This is the volume without decimal places (which makes more sense to me
than $V and should have been the output of $V in the first place).

Fix bug with dynamic label variables $p, $s and $e in Win32 GUI.

There is no reason to assume that there is nothing but the variable
in the label text. These variables must (like all the other ones)
be handled as a part of the label text.

Add new dynamic label variable $P.

This is more convenient than using $p, $s and $e
(which we leave for the sake of compatibility).
