Major changes. More info in the description

* I changed to filestructure. Instead of single files we now group our
files based in module/functionality.
* Refactor serverxml_to_json. Even though the file still ships with the
project, we app actually uses my hosted version at
http://technik.io/tron/serverxml_to_json.php . This allows user to don't
have PHP installed to still host this app themselves. Apart from that I'm
also using memcached, meaning that latency is almost non existent or so
small that it can be ignored.
* Along with refactoring said PHP file, I removed everything
country/resource specific from the parameters. The script only parses a
xml file and outputs JSON. Everything country specific will be handled by
the app itself. This makes both the clientside and the backendside code
much cleaner (just look at the ServerDataFactory) and gives us more
flexibility
