Makes Strippers Cheaper To Get (#4087)

## About The Pull Request

Lowers the iron cost of stripper clips in the autolathe to 1,000 iron
units (from 10,000 iron units) (Note the autolathe material inefficiency
still adds cost).

## Why It's Good For The Game

Stripper clips are intended to be disposable. This new cost should
reflect their nature as cheap pieces of stamped steel.

## Changelog
