Updated the scraper to now scrape all proposed budgets (the ones presented at Prinsjesdag) for 2012, 2013 and 2014 while finding the pages which contain those budgets by itself (instead of manually specifying them). Also the department code and name and the year are added to the BudgetItem as this info is required by the visualisation. The old 2013 scraped results are removed and the new scraped data is added.
Created a Perl script which converts the crawled data to csv files which can be used as input for the visualisation. Those resulting csv files are also added.
