Scrapping of Letni kino MDB

- Scrapper downloads pdf from programme page then runs pdftotext on it and parse information eventually.
- Pyocr was not possible to use because of messy result from parsing image.
I found this article (http://theprogrammingbutler.com/blog/archives/2011/07/28/running-pdftotext-on-heroku/) about running pdf to text on heroku.
I tried some other possibilities like python libs dedicated to parsing pdf but the layout of result was broken.
- There is binary of pdftotext which was compiled on Heroku and added to the source code.
