    Fixes toggle behavior in Network Topology graphs

    Changes the buttons (Toggle Labels and Toggle Network Collapse)
     in the network topology graph view into bootstrap styled checkboxes
    (the buttons should now operate as on/off) and modifies the relevant
    js code to prevent random un-toggeling on data loading. Additionally,
    the states for each button should now be respected on page refresh.
