Updated Trust Stores, Java added

This is an update of the root certificate stores. Date from each store
is from yesterday.

Description update.

Also the Java certificate store was added. Previously Java was omitted
as it appeared not to be complete. I tested successfully this store.

+Google Chromium uses basically the trust stores above, see https://www.chromium.org/Home/chromium-security/root-ca-policy.
+
+If you want to test against e.g. a company internal CA you want to avoid warnings from the certificate stores here it's recommended to use ``ADDITIONAL_CA_FILES=<companyCA.pem ./testssl.sh <your cmdline>``. (The former mechanism was to put the company root CA certificate here.)
