[Pki-devel] [PATCH] 547 Refactored CRMFPopClient.

The CRMFPopClient has been refactored such that it is easier to understand and reuse. The code has been fixed such that it can read a normal PEM transport certificate. It also has been fixed to parse the request submission result properly. The client-cert-request CLI command was modified to support CRMF requests. The MainCLI and ClientConfig were modified to accept a security token name. The pki_java_command_wrapper.in was modified to include the Apache Commons IO library. https://fedorahosted.org/pki/ticket/1074 -- Endi S. Dewata
