Replaced wget with libcurl!

Now uses libcurl instead of wget, should work much faster and safer now.
Wget code is still present and you can use it instead of libcurl, just uncomment wget sections and remove libcurl ones.
It doesn't overwrite .json files now and makes a backup each time, so if you don't want to archive text or don't want to clobber your archive you should remove strings responsible for that - they are marked with a comment.
