Use CURLOPT_TIMEOUT, CURLOPT_CONNECTTIMEOUT instead of same *_MS functions.

The *_MS (milliseconds) functions were introduced in cURL 7.16.2. but a lot of Linux distros still use cURL 7.15.*. In order to make this work on CentOS, use the options without _MS. They are not needed since the number is anyways multiplied with 1000.
