Re: Versioning w/ Oasis

If you're going to add new fields that will change file formats, its
a hell of a lot quicker to just alter your *edit_save_to_disk functions
to insert default values into the new fields, save every zone, fix the
rest of your code to read in the new format, and boom, you're done.
No hand editing, and no need for 50 different versions of the parse_room
function because of added fields.  Having to maintain some semblence of
order in db.c where you need any number of version of parse_room because
of multiple format changes would be a hideous nightmare.
