Slightly increases the fire rate of the Murphy because Obi-Wan Kenobi told me to once (also reduces AP). (#5467)

## About The Pull Request

Reduces the fire delay of the Murphy from 5 to 4
Reduces the AP of the Murphy bullets from 20AP to 10AP.

## Why It's Good For The Game

The gun honestly feels a little clunky, especially during lag. An
increase in fire rate should help it. Hopefully this isn't too strong.

## Proof Of Testing

Untested. If it compiles, it works.
