Version 1.3.13b

- Significant reduction in cost of the Advanced Large Cannon (Silver Coil cost halved).
- Slight reduction in cost of the AI Resource Collector and the Hyperium Powered AI Resource Collector (reduced coil cost).
- Reduced blueprint cost of the AI Resource Collector and the Hyperium Powered AI Resourse Collector.
- Made some of the Advanced Point Defense projectile stats relative to the vanilla stats, which should help make ETTM more compatible with mods that edits vanilla stats like range and damage.
- Made some improvements to the descriptions of the Advanced Railgun parts.
- Fixed an issue with the roof sprites for the Advanced Boost Thruster, it was using the wrong roof sprite since the vanilla Booster got updated. Has no effect on gameplay.
