Translate dropdown data

[RandomTannenbaum]

There are a few places where dropdown items are not translated yet. These are the ones I have found so far:

• Person edit form
  • The default case in the person role level dropdown is Keine in all languages
  • The options of the company dropdown
  • The names of the languages in the language skills dropdowns
  • In the language level dropdowns, the options Keine and Muttersprache are not translated.
• Person export form
  • The Cities in the location dropdown

On a sidenote, the word Kategorie in the create skill form doesn't seem to be translated.
