* treewide: http -> https sources
This updates the source urls of all top-level packages from http to
https where possible.
* buildtorrent: fix url and tab -> spaces
Some of these should be longDescriptions, but most others just
shouldn't contain newlines. E.g. write
description = "Bla";
and not
description = ''
Bla
'';
This pollutes "nix-env -qa --description" output.
