Minor AI Improvements

The core aim of this mod is to improve the actual AI behaviour without giving free money or bending the games rules. This mod started as a few minor AI fixes for specific TD units; Gunboats, Orca/Apache, SAM's and Engineers that I built in order to get my TD SP level to function better. Since then I've also included an overhaul of the TD Skirmish AI. Feel free to roll these into any other AI improvement compilations, the changes are on Github at: https://github.com/screamingchicken/CnC_Remastered_Collection/tree/CnC-Minor-AI-Fixes The changelog was getting too long for Steam, so a summary is below and more complete details on the functional changes are in a text file in the mod folder. v1. 6 12/03/22 AI counters against helicopter rushes The AI now knows how to suspend Unit/Building construction, or abandon it entirely in order to divert funds/construction to AA defences. It also has a slight tendency to throw some AA defences up just in case. This all means it can swap to constructing AA defences much faster if the player throws down 3 or more Helipads in a row and attempts a rush AI recovery from zero harvesters Now the AI can assess if it's run out of Harvesters and will move through a workflow to assess what can be sold or suspended in order to raise money. It will try to sell off the less useful buildings first. Sounds simple, but was a giant amount of code. Re-fixed Repair thresholds for custom maps again Should be properly fixed this time. v1. 5 27/05/21 AI Units no longer trapped by cheese Walls Previous Behaviour In the past, the AI didn't know how to target Walls. So a human player could build Walls up to their base, or across any chokepoint and the AI would stop there. New Behaviour Units/Infantry will shoot enemy Walls they are adjacent to if there are no better targets in range. This also applies to Units/Infantry undergoing Team orders. Some notes: - This doesn't apply to player Units, as sometimes you want to build in the enemy base. - This doesn't appl
