Added primary key warning + minor fixes
Added primary key warning + minor fixes

I spend quite some time figuring out why Deepstream couldn't find any records after a restart. In the end I found out, that this plugin sets the primary key to the Deepstream ID and uses this to get the records. Because I created the table manually, the primary key was the default "id" field. I also did a few small corrections. Kr. Jens
