ENH: Improve find_package version numbering

Make the number of version components specified explicitly available.
Set variables for unspecified version components to "0" instead of
leaving them unset.  This simplifies version number handling for find-
and config-modules.  Also support a fourth "tweak" version component
since some packages use them.
