[SUGGESTION-MSN] - Mercury bioflight

[Sabratha]

Yes, this is the "Ham the chimp" suggestion. Let's have an option for an unmanned mercury suborbital that will have the bioflight goal, makes sense imho from a gameplay point of view, as the USSR will have an early shot at this goal with Sputnik 2 and Korabl-Sputnik. If the americans do not get a chance to make this goal with a mercury, the Soviets will always end up the first ones to get it and that's not fun from a competitive campaign point of view.

The mission itself is pretty simple and no-nonsesne. Doesn't really need any new graphics, might just add a few chimp sounds at the end of the mission during recovery etc.
