Conditions are now condition values; condition groups are conditions.
Types are now terrain. Slots are first-class things.
Encounters' condition values and slots' conditions have been broken off
into their own tables, as HG/SS has several slots affected by multiple
conditions.
Finally! Location order is the same as from the old dex, which was
something like the game but ultimately arbitrary, so it's not any better
now.
This takes a very different approach to storage, rather than copying the
game exactly and trying to fix everything in code. Comments coming
shortly so other people can actually make use of this.
