Davison AAF - Fort Belvoir, VA (KDAA)

By request, here is an improved version of the stock Davison Army Air Field. I added Military_Cargo and Military_Combat parking spaces. I added the fire station and fire trucks. I removed and replaced most default buildings, added additional buildings and moved the control tower. Added static fuel trucks, helicopters, parking lots with cars and light poles. Added, removed, or adjusted taxiways and aprons.
