rework atm integration to ease syntax (#89)

split atmophere and turbofan to help cases where turbofan would be integrated in other contexts (test rig)
add TurbofanWithAtm system for convenient use of Turbofan with Atmosphere
change default psi value for booster using phiP
update buggy demo notebook: set targets values before adding targets to the solver itself
update tests
add .html file to gitignore
update HISTORY
