v2.2 (Custom Civ bug fixed!)

I fixed the bug which prevented the custom civilizations from being displayed by providing custom civ data with the download. The installation became quite a bit more complex, but hopefully the scenario is worth it.

Along with making civilizations display correctly I :

1. Added some events for different factions of the White Army to reunite under the All-Russian Provisional government.
2. Reduced the number of troops assigned to participants at the start.
3. Did some balancing.

Everything should work fine now (given that the installation is done correctly), so come play some Eurasia 1918!
