Thanks to Juho and Timo!

it's already happening in event.php

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

New translation: funds.

Translated messages for error pages (404, ecc).

We have no single page (any more) which actually is translated into Kurdish
language, so we remove it.

It should only be 0 if there was a successful build, otherwise the cron
job will deploy a potentially broken previous build when no git change
is detected.

After the build of a file has failed, remove the output file, so it is
retried at the next build again, even if the corresponding source has
not changed.

This change makes sure that the build script will stop if an XML parser
error occures, and the faulty build will not be propagated to the web
server. Please note that it requires switching all the shell scripts to
bash.
