More logging for simulator selection and deployment (#596)

* remove wrong comment about default emulator

* add logging about deployment

* add comment back, minus wrong default

* quote target string

* log simulator start command

* prefix log from simulator to make it recognizable

* add missing space in command logging

* fix log prefix (data comes from ios-sim, not simulator)

* use patched ios-sim with additional output

* fix package.json maybe?

* switch to janpio/ios-sim#802

* better logging about target

* fix

* fix eslint stuff

* try to use superspawn instead of cp

* stdio=pipe

* iterate

* Update package.json

* review feedback

* Minor improvements to logging
