	- added more info on the front page

Fri Nov 17 07:25:33 EET 2006
	- js: pop up tracked target info balloon only after centering on the
	  target, so that the balloon will (hopefully) fit and will not
	  abor the pan by doing it's own autofit

Fri Nov 17 17:09:54 EET 2006

	- js: when first searching a callsign, jump directly to the right
	  location instead of going via the initial default view

	  info balloon and let it do the minimum required panning, instead of
	  triggering panning myself
