gcyr extras

gcyr-extras is an addon mod for gregicality rocketry. At present it does two things:

• adds 4 additional tiers of rocket & tank
• adds two multiblock "miners" for use in orbit dimensions
• registers rocket fuels from GT-- as usable in rockets if present

The additional tiers provide modpack authors with extra flexibility in gating custom planets/systems. No recipes are provided for the additional tiers.
