Lots of bug-fixes

Well, there have been some very fruity happenings with L3DT 2.3c, including crashes, dialog boxes rendering at the wrong size (deja vu), ini files haven't been loading, map sizes have been lost, and maps have been saving in strange places (or not at all). Best of all, most of the faults have been both intermittent and system-dependent, which has made debugging so much more fun.

Anyhow, my thanks go to the members of the users' community who pointed out the bugs. I think most of the bad stuff has been fixed now, so I've uploaded a new installer (for L3DT Pro, only), and I recommend all registered users to update as soon as is convenient. I'll update the Standard installer some time next week.
