freeze result should order packages by (normalized) name, not the formatted line

Currently git+ requirements will all be put together. Not very straightforward.

The output format could also use some improvements. Those VCS requirements, for example, could have a comment in front of them with the package name. This would be much easier for human eyes to parse than having to find the #egg= suffix.

Also see pypa/pipenv#2818. (The template would need to be configurable as well.)
