Force carrier planes to start at +1s (#1600)

Browse Source 
Forces carrier planes with original start_time of zero seconds to have a start time of 1 second. This will prevent them from spawning on the 'sixpack' and functions as a workaround for a DCS problem (deadlock / traffic jam).

Fixes #1309.
