Adds a spraycan to robotics (#87412)

## About The Pull Request

This PR adds a single spraycan to every roboticist office, and a
screentip that should tell the player that they can restyle augments
with it, should they hover over one. This spraycan has a new sprite,
which is a small edit of the existing spray can, just wearing the
colours of the roboticist jumpsuit. The can's description also mentions
restyling robotic limbs.

This PR also fixes a bug: Peg limbs also brought up the restyling menu,
albeit, every radial button was empty, and clicking on one runtimes. Now
you can no longer do such a thing.

Future improvement: perhaps making augment restyling cheaper would be
nice, but I did not want to add that into this PR.

## Why It's Good For The Game

This is a rarely used feature, some folks thought it has been removed
when the augment painter has been removed from the game. Putting it in
front of the players will make it used more often, and might result in
new augment styles.

## Changelog

add: Adds a roboticist spraycan, and adds one of them to robotics on
every map
qol: adds a screentip to spraycans that tells you that it can restyle
robotic limbs
