Try to make the various param files to follow similar namings:

    - Lowercase the few ones using uppercase
    - Use dash to separate name components
    - Start with "copter", "plane", "rover", etc instead of the mix we
      had
    - Remove "params" from the filename since it's redundant with the
      extension

and simplify startup using defaults file

this will give us the ability to analyse any EKF errors

this prevents problems on windows with virtualbox. It tries to run
JSBSim as the directory 'jsbsim' and fails

this is now needed to get timestamps from JSBSim

this led to a race condition where some parameters were not loaded as
they were being sent with the wrong system ID

trying to debug an autotest issue

we need to wait for a full GPS fix

pitch 80 may not be reached due to granularity of the MAVLink logging
