Add support for CONTRIBUTOR in ACDD
CONTRIBUTOR should have the same variables (and syntax) as CREATOR. CREATOR is meant as PI while CONTRIBUTOR is for those who provided assistance.
The PUBLISHER field should be filled as SLF, etc from the web service in order to be able to group all data that has been published by us (we need to find a way to let it be done automatically on the web service. Maybe using by default in MeteoIO an environment variable and having the web service setting this env. variable?).
