Fix pastebin (#753)

* Added pastebin license, add BSD 2 clause to list of licenses.

ZeroBin is now PrivateBin updated links.

* add Snipt full stop

* merge bsd-2clause/3clause licenses

do not differentiate BSD licenses.
We don't know whether previous entries are under BSD-2 or 3.
The only difference is:

> 3. Neither the name of the copyright holder nor the names of its contributors may be used to endorse or promote products derived from this software without specific prior written permission.
