modified JSBSim fw sim to easily use either defaults or an initialization file, launch velocity can now be specified in SIMU section, added example intialization file, modified jsbsim.xml example airframe to use init file and updated to include firmware section instead of old makefile section

This file sets up the aircraft initial conditions.
Allowable units are:
Length: M IN FT
Angles: DEG RAD
Velocity: M/S FT/SEC KTS
Area: M2 FT2
Volume: CC LTR M3 IN3 FT3
Mass/Weight: KG LBS
Moments of Inertia: KG*M2 SLUG*FT2
Torque: N*M FT*LBS
Force: N LBS
Spring Force: N/M LBS/FT
Damping Force: N/M/SEC LBS/FT/SEC
Power: WATTS HP
Pressure: PA ATM PSI PSF INHG
Some example initial conditions are given below. Not all are needed.
Note that the launch condition body aligned forward velocity is given in sim_ac_fw.c
and can be defined in the SIMU section of the airframe file. See jsbsim.xml for example.
Other ICs are allowable, see JSBSim source for more info:
