    core: fix HTTP proxy authentication autodetection
    
    It seems the openvpn doesn't want quotes here, despite the manpage
    indicating that they should be used:
    
     --http-proxy server port [authfile|'auto'|'auto-nct'] [auth-method]
    
    so just strip the quotes off.  The error we get using quotes is:
    
    WARNING: cannot stat file ''auto'': No such file or directory (errno=2)
    Error opening 'HTTP Proxy' auth file: 'auto': No such file or directory (errno=2)
