Changes some mods' planet names around. Made mostly for personal use.
Name changes:
- Maraxsis -> Thala
- Tellus -> Zhigao
- Pelagos -> Ghillie

Specifically, "Zhigao" and "Ghillie" are names from my Minecraft planet mod, "Diggyfactory Planets", of planets that are pretty similar to Tellus and Pelagos so it's #fairs mate. Or whatever.
