Set errorlevel to -1 report all php errors (including errors which are excluded from E_ALL (E_STRICT prior to 5.4)
Mostly phpunit improvements:
* removed obsolete function jrxmlAction it is moved to the report controller and update download.phtml
* check if layout helper is definied before disabling layout (provides error for phpunit)
* add Webenq_Model_ prefix to class ReportPresentation (provides error for phpunit)
make method getQuestionnaires static, no need to make it instantiatable.
add basic unit tests for methods in questionnaire controller: is the correct action used (don't we get an error)
