Add map chopping block (#4143)

Resolves #4080

## Description:

Add Map Chopping Block
https://youtu.be/NpX73lHiKO8

Increased multiplier for 4 player team games and water nukes (plug in
center among other shortcuts). This map was made as a faster alternative
to Labyrinth. Map has been modified since last submission to be 'less
crazy'.

## Please complete the following:

- [X] I have added screenshots for all UI updates
- [X] I process any text displayed to the user through translateText()
and I've added it to the en.json file
- [X] I have added relevant tests to the test directory
