[wip]New repeat patrol fix

[Ducimus]

I've been quietly working on a new repeat patrol fix, which i think is a little more robust then my previous. Although im not sure how it will work out. The idea is to present TWO missions for the game to choose from, and have them available on a 3 month window, before shutting those down, and opening two more missions for the next 3 months. This way, the game concievably always as a choice between A, or B, and is forced to choose C, or D, after the next 3 month rotation. I have two worries however.

- i'll bet what happends more often then not is the game always picks one assignment over the other

- 3 month window on missions. Might be too wide of a window. ALthough I found it neccessary because on a 2 month window, quite frankly pickings on missions so they arent consecuitive become a bit slim.

However, there is no forcing of special missions, either the game picks them, or it doesnt. Heres the template ill be using for pearl harbor for this version, tell me what you think.
