Stop gap fix for AI speed to nav points.

Browse Source 
This isn't a great fix for the reason I mention in the comment, but it's
quick and actually is accurate since it looks like we don't actually
handle formation speeds correctly in most cases...

This is probably as "fixed" as this is going to get for now since most
of the flight planning code is in the process of being rewritten.

* **[Flight Planning]** Patrolling flight plans (CAS, CAP, refueling, etc) now handle TOT offsets.
* **[Mission Generation]** Restored previous AI behavior for anti-ship missions. A DCS update caused only a single aircraft in a flight to attack. The full flight will now attack like they used to.
* **[Mission Generation]** Fix generation of OCA Runway missions to allow LGBs to be used.
* **[Mission Generation]** Fixed AI flights flying far too slowly toward NAV points.
* **[Plugins]** Fixed Lua errors in Skynet plugin that would occur whenever one coalition had no IADS nodes.
* **[UI]** Fixed deleting waypoints in custom flight plans deleting the wrong waypoint.
* **[UI]** Fixed flight properties UI to support F-15E S4+ laser codes.
