LIB Scenarios have incorrect altitude for some flight plans.

[checkandmate1]

Example flightplan in the LIB scenario:

{
          "airlines": [
            {
              "icao": "JBU"
            }
          ],
          "altitude": 360,
          "destination": "KPBI",
          "exit": "WHITE",
          "route": "ELVAE COL WHITE J209 VILLS J209 SBY J79 KATZN ISO J121 CHS CAKET Q97 DEBRL Q97 MALET DDANY STOOP"
        }  

The altitude is 360, which causes a lot of issues, both with it's climbing and the airspace awareness rules. Along with changing the individual scenario, also adding something that checks the altitude in spawnAircraft() in sim.go, that if the altitude is less than 1000, it will multiply its altitude by 100.
