Shuffle "use IPDB;" and "use MyIPDB;" lines so that we can
automagically insert a suitable "use lib..." line during 'make install'
Check copyright statements
Clear up some defaults, and place a number of "constants" in IPDB/MyIPDB
rather than having them hardcoded all over the place
(Still need to think of a sane way to do this for ipdb.psql's alloctype
preseeding)
Tweak $VERSION identifier in IPDB.pm so it can be defined in the Makefile
Clean up some dangling bits from repository history conversion, remove
unneeded "use ..." statements
Tweak rWHOIS export script to use more globals and "constants" from
(My)IPDB.pm, and more Perl internals than system()-equivalents. Add a few
fixme comments for longer-term flexibility improvements.
