Generate setup.ini based on aribitrary date and/or time

[maphew]

I released a new pkg-apt testing package today. When I started setting up an environment to test what it will do in an upgrade situation I realised I need to put Osgeo4W into an older state, which means installing no-longer-current packages first. This isn't so easy.

I think the easiest approach is likely to be to adapting osgeo4w-regen.sh and genini to generate a setup.ini based on a date stamp. Then issuing an instruction like regen.sh 2014-06-01 would crawl the release package tree, ignore any files newer than said date, and generate setup_2014-06-01.ini.

I scanned genini for likely places to put a date filter, but my perl is too weak for the task. ;-)

genini now has a --date=yyyy-mm-dd argument and ignores older files.

regen.sh wasn't updated and you'll have to run genini manually like this:

Note that that produces more entries like the one from #457, because that apparently wasn't fixed yet and the nightly builds are cleaned up regularly and there are no files left for older states.
