contains the (root) certificates of most major Certificate Authorities. It is basically
the default curl ca-bundle.crt plus cacert's certificates.
The 'curl-ca-bundle.crt' will be copied to the installation dir if needed.
It will from now on be used by Unreal for all remote includes (curl) related certificates.
If you want to use https but don't want to buy a certificate, we suggest you to apply for
a free certificate at CACert (www.CACert.org). Or, alternatively, add your own certificate
(PEM encoded) to curl-ca-bundle.crt, see 'SSLCERTS' in the curl package for more info.
