B-dtl1-2.tga was upside down in br-capships.mat, which caused the Bretonia Battleship to look a bit strange sometimes. Additionally, both textures in br_turrets.mat were generated without additional mips. Both issues have been fixed in this commit.
Adding this effect was deemed to be impossible without crashing while playing on vanilla servers. However, a different approach has been taken by replacing existing unused select_equip.ini entries. As long as no new ones are added, crashes on vanilla servers won't occur.
Essentially made the lights twice as large. Also the green light blink every second or so. I couldn't create new lights since that would cause crashes on vanilla servers. Instead I edited and used existing lights. The TradeLaneGreen light isn't used anyway. This commit also fixes an issue where trade lanes in some Border Worlds systems were missing 2 green lights. Those have now been added.
