Limited amount of projects per page

[martinszy]

I don't know why exactly, but when I parse the projects list with Nokogiri, I only get 63 projects instead of all the available. More debugging is needed. By now pages are limited to 64 results, but the API allows for at least 1000. That would save requests when having to re-parse all the projects.
Re-parsing is needed due to a lack of a list of updated projects by the congress. We need to re-parse all and take what's changed.
