Alt+wheel and moving network don't work if mouse outside SVG canvas #44

Alt+mouse wheel only zooms the network graph, if the mouse cursor is inside the network graph, which does not cover the whole network tab area especially when the network is zoomed small. This should be changed. Regardless of whether the cursor is inside the network or on another spot of the network tab canvas, Alt+mouse wheel should zoom the network graph.
