* arts-2-1-536

* src/absorption.cc (calc_gamma_and_deltaf_artscat4):

Only send the warning about the total VMR being more than 10% different
from 1. to out2 if the user can actually see it (verbosity>=2).
Speeds up arts.ctlfile.xmldata.surf.mars by a factor of 2 because the
warning happens 11.8 million times. This output is unlikely to be ever
seen because it only appears inside an agenda. Only running arts
with -r202 will make this warning visible (and produce a 1.3 GB rep
file). I think we'll have to rethink our logging strategy.
