ATIS upgrade

Add missing ATIS elements (transition level, expected approach,
precipitation, runway surface warnings).
Minor phraseology fixes for US/Europe.
Adds "/sim/atis/concise-report" option to use abbreviations (CAVOK etc),
and omit "obvious" units (depends on airport).
Trigger ATIS updates for significant pressure changes.
