    Bug 25658: Replace security slider with security level UI
    
    This patch has security level related changes for torbutton.
    Migrated 'security level' related strings from torbutton.dtd to new
    securityLevel.properties file, loaded by JS in the new securitylevel
    component in Tor Browser. Removed the old Security Slider xul and menu
    entry in the torbutton menu. Also 'fixed' the german (de) torbutton.dtd
    file (was valid listing of XML entities, but it broke my dtd parser used
    to migrate strings)
    
    Added new "extensions.torbutton.inserted_security_level" pref to
    torbutton that piggy backs off the existing
    "extensions.torbutton.inserted_button" pref logic. Toolbars are reset to
    the Tor Browser default when the new 'inserted_security_level' pref is
    false. Coupled with the changes in tor-browser, users which upgrade will
    have their toolbars reset to the new design.
