adjusted AI SAM site repairs:

- SAM sites are no longer repaired instantly when AI takes control of a sector
- repairs begin 24 hours after the AI takes control, and repeat every 24 hours until the SAM is back at 100%
- repairs can be interrupted by the player regaining control of the SAM site
- time to repair a fully-destroyed SAM site depends on difficulty: novice takes 5 repair cycles, experienced takes 4, expert 3, and insane 2
- moved RepairSamSite() from ASD.h (where it was unused) into strategicmap.h
- this sets up the existing but previously unused strategic event hook EVENT_SAMSITE_REPAIRED
