Some memory leak

Script.dat (global) was full of a million lines of junk, which slows save/load significantly

Anecdata, but we've noticed horrible save/load performance when using Mining Drones with this mod on a 500 SPM base that progressively got worse. Inspecting the save file reveals millions of lines of floating damage text entity junk as well. It seems that Mining Drones causes text to pop up and makes this issue more obvious.

Thanks for alerting me to the issue. I've released a patch that should fix the leak and has a script to remove junk already in the table.
