Added soviet 01 to the Red Alert campaign

I added all cut scenes mentioned in the original scu01ea.ini file. The C# scripted version left several out. Fixed all the bit rot with auto upgrade rules and lot's of manual tweaking. Condensed the rules to make them easier to understand and more robust. Added the flare that is presented in the cut scene. You will note that I made this a little less scripted. Compared to the original the yaks don't just appear, you have to build them yourself. The paradrops are manual. In summary this should be a gentle modernization.
