[trunk/7.0] Print survey response has no context

[Jordi Llinares - KM Sistemas]

(Also affects to 6.1)

In survey module, survey_browse_response class fails to pass the context to the parser. Code reads

rml_obj = report_sxw.rml_parse(cr, uid, surv_resp_obj._name, context)

rml_parse is initialized with two optional arguments before the context: 'parents' and 'tag'. A not explicit enough call to rml_parse leads 'parents' to receive the context. It should read

rml_obj = report_sxw.rml_parse(cr, uid, surv_resp_obj._name, context=context)

In the practice, if you try to modify the survey response report adding a datetime field, it'll always be shown in UTC, because context_timestamp method receives an empty dict.

Sorry not formatting the code or using a more standarized way to propose the patch. I don't use bzr+ launchpad (I absolutely prefer git +bitbucket).
