Extra content downloading interface

[michelebucelli]

That's something pretty new... There should be an interface to download extra content from a script file.
For example: you download from the internet a text file containing a series of instructions like:

download [url] [destination path];
install [level pack id];
kill [file];

Something like a downloader for extra content... It should make it easier to share new levels or level sets, or to release content updates.

What's more, the game should provide a way to connect to the internet for update checking - for example, reading a file here on the github repo that lists all the content packs that have been released. For each pack, the game would check if it is installed and available or not, and if not it downloads it.
