New Mod: Build-A-Battle

New build attached, with a few minor tweaks:

• The Horde Mode UI now has a "High Score" display, and the high score is now saved in flux.ini; previously it was stored in the save file, but that meant it usually wouldn't get saved, since horde mode typically runs until the player dies (at which point they can't save, so the score wouldn't get saved).
  
• I decided that I might as well go for as close to a 1:1 creation of the "Instant Action" functionality as possible, and added functionality for automatically spawning in friendly wingmen (every third wave) by default -- with an option in the UI to disable them.
  
• I adjusted some of the default horde mode settings as well, bumped up the default "escalate waves by" factor to 50% and decreased the default spawn distance to 15km.
  
• And there is now "DisplayDebugShipList" in the mod's INI file, which controls whether or not the "DEBUG (All Ships)" category is shown.

Functionally, I think it's pretty much finished at this point, and I'm planning to do some final polishing (put together a readme file, etc) over the next few days & post to the mods archive here. The only other additions/changes I think of would be adding some config options to the INI file, to control the contents of the "DEBUG (All Ships)" category, in case people want to use that to create a custom "fav. ships" menu (or maybe define that in an external text or CSV file, the latter would presumably allow setting labels for the ships rather than just displaying the internal resource name). That, and moving the various UI/HUD text strings into a external CSV file, which would allow for localisation/translation, if that's something anyone is interested in.

Overall, it's been quite an interesting experience getting this built. The original concept was mainly just for a simple "ship spawner" as a companion tool for testing out another mod I had in mind -- and gradually grew into a more or less full recreation of the Instant Action game type, and a test-bed for functionality for another mod I've started working on. It's also been helpful in terms of getting a better handle on what is & isn't doable with POG scripting, UniGUI, etc.

Anywho, latest build attached (2026-11-13.2114) along with a screenshot of the updated horde mode UI.
