The certificate to the certmapping might be inserted as
base64 encoded blob. This patch allows to also insert the certificate
blob with surrounding "-----BEGIN CERTIFICATE-----" and
"-----END CERTIFICATE-----" lines. This behavior is the same in
widget for assigning certificates to users, so the change helps
WebUI to be more consistent.
