Preparation for a new release

1. Updated the dependency on corneltek/curlkit to the latest stable release as required by PHPBrew.
2. Added a development dependency on PHPUnit.
3. Added Travis CI configuration.
4. Fixed tests (removed the usage of pear.corneltek.com since it's no longer available).
