Deployer "if-else"

[ndehio]

When writing ops-files for the deployer, I am missing a very simple "if-else" feature.
Without that feature it is annoying and time consuming to quickly test different controller options for the same scenario (e.g. connecting portA or portB to another component, for example for sending a Jacobian with/without orientational part)

[ndehio]

The solution is actually pretty simple... (thanks to my masterstudent William!)
@xwavex, please add this following example for spawning multiple robots at once (demonstrating the if-else feature and a for loop) to the documentation.
