Allow silicons to click drag discs into cloner

[Jimbo20]

They can take cloning discs out of the rack but cannot insert them into the cloning computer, I tried last round with my cyborg shell (unless I somehow did it wrong)

Not sure if this is an intended behaviour or not, but feels like a real nerf to silicons if it is. 
Since you can see the red light and all but can't do anything about it without assistance.
