Reorganization and list of D libraries (300+)

[Fra Mecca]

Hi all.

Lurking in this forum I had the feeling that lots of D developers 
tend to rewrite lots of code that could be found in libraries. 
This is not bad per se but I thought that one of the reason could 
have been the current process of library discovery.

For this reason I have edited a list of libraries that could aid 
in this process.

I also considered that the following features could be of 
importance to you:
- License
- Garbage collector
- last modification (automated)

The list is of course not complete and I could not test all of 
the libraries I included.

I welcome you to modify it, open PRs or issues on github.

I hope it could lead to a better ecosystem for the whole D 
community.
