Neighborhood: version up maze and add take paint command

[molly-moen]

This PR gets version 2.4.0 of Maze and adds the take paint command to neighborhood. Take paint takes paint from a paint can and adds it to the painter's supply.

The paint can addition on Maze can be seen here. We were already doing the styling of the units on a maze cell (ex. for collector) on the code-dot-org side, so I added an additional class on the paint can value on the Maze side and added the relevant css here so we can resize the font for Neighborhood.

This PR updates our neighborhood levels (allthethings Javalab 1 and 3) to include paint cans. I resized level 3 from 16x16 to 15x15 (our max size that can include a paint can) and changed the background images a bit, along with adding paint cans.

Java Lab 1 now looks like this:
