Issue77 durack1 add cmip5 json dicts

@doutriaux1 merging this PR as I'm just updating CMIP5 jsons as provided by @gleckler1.

@gleckler1 it would be useful to commit to the repo files used in generation of the clims and the json files themselves.

@doutriaux1 this was one of the last steps before tagging to 1.0.0 release
