* pkgs: refactor needless quoting of homepage meta attribute
A lot of packages are needlessly quoting the homepage meta attribute
(about 1400, 22%), this commit refactors all of those instances.
* pkgs: Fixing some links that were wrongfully unquoted in the previous
commit
* Fixed some instances
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.
