Facilities upgrade in Proportions 2.5+

[PvK]

Sorry this took me a while to resolve, oleg.

I tried to keep my Roman numerals, by rearranging the order of the facilities and making the old ones inaccessible. Unfortunately, this only works for upgrades from level I and II facilities - level III facilities would not upgrade to larger level III facilities, because SE4 would see no higher Roman numeral, and therefore not offer any upgrade.

SO, I trashed all that, and made a simpler change, although it may be a little more confusing for the user, specifically:

I just changed the Roman numeral values. I didn't even change the names. So, for example, Mineral Miner Complex I now has Roman numeral IV, and Research Megacomplex III has Roman numeral IX, etc.

I think I will release a new Version tomorrow, which will be backwards-compatible with 2.x, and will have several new items and fixes in it, including this.
