SAK-21624

First cut at the Javascript in-browser checking.

Rename the cachetimer for the in-server check to be 

iframe.xframe.cachetime=7200000 

Add new parameter here;

iframe.xframe.loadtime=4000

The amount of time the browser will wait before checking to see if the frame 
load has at least started.

I think the JS needs a bit of tweaking still.
