KSamsok-PHP 0.9

I just took the time to release 0.9 of my KSamsok-PHP library and to update the documentation.

This release has breaking changes for those who extends the KSamsok class. This version brings increased speed and updated tests which are now connected to Travis. Also PHP type hints and modern array syntax is now in place.

Because of the major speed improvement this is a much recommended release. For those who are only using the existing methods and does not extend the core class no changes are needed. For everyone else, please note that the prepareUrl() and validResponse() methods has been removed. For more information see extending KSamsok-PHP and the breaking commit.
