Generate altitude limits arrays dynamically to support planet adding mods and potential future canonical worlds.

Modified TimeControlSettings.cs to generate altitude limit arrays dynamically, taking into account the number of bodies that are in the game.  Modified TimeControl.getPlanetaryID(string) to search the localBodies list for reference ids instead of hard coding values, the the body's index in localBodies *IS* the reference body id.

These changes enable support for future planets Squad may or may not add, and for planet adding mods such as the upcoming Kopernicus mod.  Planet Factory probably won't play nice due to its own implementation of warp level modification.
