Steps to reproduce the issue

Access a test api such as https://dev.api.ean.com.

Expected result

Access the REST endpoint without error.

Actual result

The underlying cURL application is throwing an invalid certificate error.

System information (as much as possible)

Joomla 3.3.4
Ubuntu 14.04 Server
curl 7.37.1-1ubuntu3.2
php5 5.5.12+dfsg-2ubuntu4.3

Additional comments

JHttpTransportCurl requires additional options for toggling CURLOPT_SSL_VERIFYPEER and CURLOPT_SSL_VERIFYHOST. Whilst the issues is actually with the ssl certs being provided by the server, it is should be recognized that the configuration of many external REST providers cannot be controlled by the developer so developers should have the option to turn off this verification for testing purposes.
