Copernicus template update 7 10

[RLumSK]

Yet another Copernicus template update, this time to version 7.10. Plus (inform @nuest):

• The folder contained a .sty file. I've removed that because it was a standard file (I've also tested it), and the pull request template asked not to include those files.

• The pre-defined subsection headers, such as 'Disclaimer’, had disappeared in the PDF. The reason was that the macro in the copernicus.cls required a language flag (english, german, or french). Why this was not an issue before I cannot tell, but I think it is related to the babel package (without having further investigated the underlying change). I had also tried the LaTeX template directly available from Copernicus without using rticles, and I could reproduce the behaviour consistently. I have informed Copernicus via e-mail. Besides, the option to pick one of the three languages was always in the copernicus.cls but not used by the template. I have therefore added a language option to the skeleton template.

• Update Rd and namespace (could be done by devtools::document()).

• Update NEWS.

Thanks a lot. And for removing file.

I am currently blocked to publish on CRAN a new release because the package is now more than 5MB built. And this is the limit, so removing some content is the next step.
