Adds Very Slightly Different Icon for Abductor Send To (vs Send Self) (#94840)

## About The Pull Request

So there's two abilities in the abductor camera console that have the
exact icon. This isn't ideal. So I've summoned all my energy and made a
new graphic for one of them. (It's not very good. I'm a programmer, not
an artist.)

What we have now:

/>

## Why It's Good For The Game

I think it's largely a good thing when there's some sort of visual
distinctiveness between GUI icons.

I am extremely open to replacement sprites, but the main thing is having
a different sprite at all.
