Some bugfixes for the mod when it changes the state of raider bases.

(This may require repeating covert actions)

Added "ramping" mechanic: this to take some pressure off during the critical starting phases of campaigns and lets it become more of a factor as the game progresses to the midgame.

Added mission exclusions for Recover Expedition and Protect the Device mission types: it's one thing when there's a tiny chance for them to spawn due to having to compete with other sitreps, it's another when they have a far larger chance to consistently spawn on top of what you may have to deal with.
