Scrapers retrieves the movies from the page. It has problems with encoding.
Fixed encoding. Moved base class to separate module. Module now contains only necessary OlympiaScraper subclass.
Created base class for www.cinemacity.cz multiplexes with basic functionality.
Switched the order of the filters. When there were movies screened at multiple places at once it raised some nasty exception. Might not be the ideal solution.
