Comet with new Juggernaut

I'm pretty excited with success of with putting new Juggernaut into operation. Super-basic integration with Ext-JS works too. The limiting factor is an implementation of client-side data-store which, by default, allows only whole store reloads. It should be possible to work it around with some custom code, but I leave it for later, as I'm pretty happy what I have now.

The next step is rework SAW views with use of new Rails3 JS tricks for improved user experience.
