[2.0.21] combinator conditions, space platform conditions and train conditions should be savable and copy/pasteable

[factoriouzr]

Combinator conditions, space platform conditions and train conditions should be savable and copy/pasteable.

You should be able to save and apply pre-configured setups to all these things like you can for requests and give them a name.

You should be able to shift+right click to copy a condition and shift+left click to paste that condition into another area in the same gui.

It would be great to have this.
