    Drop environment proxy resolver to lowest priority
    
    Currently the environment proxy resolver has 100 priority. The portal
    resolver in GLib has 90 priority, the GNOME settings resolver has 80
    priority, and the libproxy resolver is relegated to last place with 0
    priority. Making the new environment proxy resolver highest-priority
    seemed like a good idea to me because environment variables are for
    debugging and surely if an environment variable is set it's because you
    want it to be respected, right?
    
    Wrong. Problem is, Console and Terminal both inspect GNOME proxy
    settings and translate them into environment variables, see console#81.
    If we prioritize the environment variables, which are unable to fully
    express the desktop configuration, then we lose out on goodies like
    web proxy autoconfig and such. Worse, this will only happen when running
    from your terminal, meaning applications will break only when run in
    Console or Terminal. Imagine how frustrating that would be to debug.
    
    Although I'm usually reluctant to make major behavior changes in a
    stable release, we should revert back to longstanding historical
    behavior. The environment proxy resolver will be used only as the last
    fallback, useful in case libproxy is not available.
    
    Fixes #190
