enhance eventregistration form

This add multiple features to the form:

- The description field does automatic HTML paragraphs and linebreaks,
  showing the text as the registrator intends
- The description field escapes HTML
- The form contains a field to select the event entry's language. This
  helps set an automatic filename
- The tag for the country contains the full country name as visible
  content
- The country field is now inserted automatically without the need to
  translate it
- The country-list template can now be extended with a CSS class
