Added error report script, and changed simpleSAMLphp to use that script.

The 'errorreportaddress' configuration option is now removed, and the user
must set the 'technicalcontact_email' to enable error reporting.

This patch introduces two new strings which should be translated, both
in dict/errors.php:
'errorreport_header': Error report sent
'errorreport_text': The error report has been sent to the administrators.

A more descriptive message should probably be set as the text.
