Pricehikes the SAW-80 (#3929)

## About The Pull Request

Oops! This is way too cheap for what it should be! At the current price
it's being purchased over assault rifles on the regular.

Boosts the SAW-80 to 7000 credits instead of 6000.

## Why It's Good For The Game

This was not intended to be sold as the SMR-80 but better. 

## Changelog
