SSL bypass verification for https feeds 

Hello tontof.
Just a little commit to bypass the SSL verification of cURL for https links. In my case, i can now load, for example, "https://www.pcinpact.com/rss/news.xml" without the message "The feed you are trying to add already exists or is wrong. Check your feed or try again later".

Thank you for kriss_feed and your work ;)
