moved leaflet to .tmp
moved leaflet from lib to .tmp
Jakefile produces a leaflet-custom-src, and a leaflet-custom.  We are now using leaflet-custom-src for development in the leaflet directory, and then copy leaflet-custom to leaflet and move that to .tmp for the build.
added code for debugging in grunt across networks.
turned zoomanimation on, by removing zoomanimation:false.  Leaflet seems to have fixed the problem, and we needed zoomanimation on for touchzoom to work on ie11.
Removed our custom code for onDown, onMouseDown etc,  and replaced with minor changes to the leaflet code in _onDown and _OnMouseDown, where we check for leaflet-box-zooming as one of the return false conditions.
changed to leaflet-custom-src as more indicitive of what we're doing, gets changed during build to leaflet
Added cancelBubble to get ie11 working on tablets,  and called leaflets disableClickPropagation instead of using .on for mousdown and touchstart
