[NTG-context] Croatian translation of core-mis.mki[iv] and m-units.tex

Hi, I translated the strings in core-mis.mki[iv] and m-units.tex to Croatian. Updated files are here: http://www.inf.uniri.hr/~vmiletic/context/core-mis.mkii http://www.inf.uniri.hr/~vmiletic/context/core-mis.mkiv http://www.inf.uniri.hr/~vmiletic/context/m-units.tex There are many more strings in m-units.tex that could (and probably should) be translated, if this code will remain in use (since Hans and Wolfgang talked about new module for units).
