Add RozpisyZapasu to list of examples

Slate is great, thanks a lot!

Documentation is in Czech language, so I encountered [ID generation problem](https://github.com/tripit/slate/issues/144). [Stackoverflow](http://stackoverflow.com/q/15686752) helped me to solve the problem. Repository is hosted at [Bitbucket](https://bitbucket.org/sports-scheduler/api), because I already have a team there.
