Map: A little artisanal map... with 1225 provinces

[Twan]

Attached new version of the map file.

* some terrain or neighbor errors fixed
* desert, tundra and rain forest sites used for provinces of these terrains (and some terrain changes, ie the frost forest provinces are now forest with a tundra site instead of forest + waste)
* all neighbors of very big cities (30k+ pop) should now be nostart

I'm waiting for the Unit ID and Sites DB lists to developp special poptypes and provinces.

I've started to prepare units for a Greyhawk mod (it will replace the units linked with many poptypes, so Oeridia will have its own recruitable indies with random garnisons made of them, the following map files giving a specific poptype to many provinces ; in addition special locations will have special guards - I'll try to replace poptypes by poptypes in relation, so if you prefer to have Hoburgs than D&Dian gnomes and halflings you will have hoburgs in their provinces if you don't use the mod -).

Anyway it's a big work and I think a final version won't be finished before some months.
