    Bug 40562: Added Tor-related preferences to 000-tor-browser.js
    
    Before reordering patches, we used to keep the Tor-related patches
    (torbutton and tor-launcher) at the beginning.
    After that issue, we decided to move them towards the end, however we
    kept TB4: Tor Browser's Firefox preference overrides at the beginning
    because it influcences many other features.
    As a result, to keep bisect working, we split that commit, and moved
    all the preferences related to Tor (such as network.proxy.*) here.
