Support for processing variables

[p-a-s-c-a-l]

ATM not even $emikat_id is supported in drupalService.js! Additional parameters have to be supported, see clarity-h2020/data-package#42 (comment) for more details.

The query parameters are set by csis_iframe_connector.js and extracted from the Drupal site by csis_helpers.module.
