Active check protocol broken when changing the name of the property data...

Active checks stopped working in this version, always I receive:
{"response":"failed",
"info":"processed: 0; failed: 0; total: 0; seconds spent: 0.000026"}

If you see the message sent to zabbix it starts with: {"request":"agent data","results":[{"hos... which is incorrect, should be {"request":"agent data","data":[{"hos

Seems this commit https://github.com/jitlogic/zorka/commit/1bf0412e1743b4f4c0a45ca0823df9e1f24dd1ed changed the active agent protocol. I've tested changed again the name and now it works.

Also other minor fixes were applied
