Fixed a bug in Henry's constant

Small error in the definition of the Henry's constant, which is used in the wet deposition routine. See forward wiki.

Prevent negative emissions over Canada

Found a nasty bug in CAC emissions. We should set the emissions to 0 when 2002 exceeds 2005 by more than a factor of three. See forward wiki.
