[WIP] Copy snippet to clipboard, package permalink

In about 15/20 days the number of badges rendered will reach the 10.000.000
in order to celebrate this great number, could be great introduce some love:

- [x] added a permalink for the repository page.
- [x] added a button for an all-in copy.
- [x] added a copy to clipboard for all the snippet.
- [ ] manage errors

The output will look something like:

Note:
@toretto460 Unfortunately I had to remove your loader ajax snippets in order to simplify (very happy if you find a way to introduce it again)
