Highchart realtime

Yes, but this is _really_ a ugly hack and I fully expect to rewrite this stuff. @kgrz is also trying to get this to work using rickshaw.js.

How this works is - graph starts with a series of 19 points on Xaxis and as objects came they are added as a series. When new object type gets added, all 19 points must have some data for that type (otherwise it does not work correctly).
