Some of theOSDH file names have changed. Some of the fields are not available anymore. Code cleanup in DBO.

still moving forward with the DBO plugin, picojson has been edited to fix the warnings (few changes), fixing a misplaced space in SetCompilerOptions

The Nakamura and Huwald algorithms in Unventilated_T were not properly implemented... This has been fixed and they should now really follow their respective papers. The DBO plugin has been a little bit cleaned up, waiting for new developments of the REST API.

Added a low level json function (getStrings) and improved goToJSONPath() so it supports arrays in the middle of the path

code restructuring in DBO to make it more similar to other plugins. Implemented a proper support for recursive METEOPATH in OshdIO (only the most recent files will be used for each time step, according to their run_date).

Added the structure for the upcoming DBO plugin, fixed an invalid copyright in GSNIO (the old plugin was ©epfl, the new one is ©slf), added a note to the oshd plugin.
