Output of -PV was not suitable for inputting to -m-, key was missing. (#1970)

* Output of -PV was not suitable for inputting to -m-, key was missing.

Fix #1969

* Make V flag to -P also print the type

This makes -PV work also for non-built-in tags (of which their type is
not known by exiv2).

* Adjust man to accomodate for the V flag change
