removes article.cls from list of .cls files for which theorem-like environments are defined since too many journal classes build on article.cls

makes loading of babel conditional in numapde-packages.sty; babel is now only loaded with classes for which we set a default language through a default document class option

updates lecture notes class to not specifically pass english, ngerman to babel, which anyways grabs it from the default document class option

restores compatbility with SIAM journal styles; removes unnecessary \GetTranslation for .cls files which will never be used in languages other than English
