Issue 2 : Enable live update

@johnregan3 and @fjarrett 

This is far from perfect but it gets the job done. I've added a new argument inside the query class to be able to query  query from the last shown ID on the page.

Quick Note : Live update only work on page 1 of the stream and only if the id order and date order is "desc" (otherwise where would we put the new row ?).

I also think we shouldn't live update if a filter is applied... should we?

Should resolve #2
