Title: Add filter for sslverify on zip url

the zip_url never gets the sslverify setting passed from this plugin, because it's not hooked into at the point when it's run. This addition will set sslverify to the config settings when WP goes to download the ZIP. Otherwise, sslverify defaults to true and fails on certain hosts that have no idea what the GitHub SSL certificate is (lol).

Props to @pglewis for digging so deep to find this fix.
