dpaste: version 0.4.0

* Fix: remove unwanted end-of-line appended to the output when using
  `-g` option to recover a blob.
* AES encryption support.
  OpenDHT's crypto interface is used as it is already a fundemental
  dependency. This implicates:
  * Key stretchting with argon2~[1];
  * AES-CBC encryption;
  * Unit tests for process(Plain/Cipher)Text functions.
* Unit tests.
  * New dependency on the Catch library.
  * Making use of travis for running them.
* Use of Msgpack for serialization of data before sending with OpenDHT.
  Backward compatibility with 0.3.3 prior to this is maintained.
* Better log encapsulation.
* GPG crypto support (encrypting, signing, decrypting and verifying data).
  It uses GpgME C++ wrapper around the C library GpgME. This library handles
  OpenPGP crypto and prompts for the user input for passphrase when needed.
* More strict dependency on curlpp>=0.8.1 and nlohmann-json=2.1.1
* autotools: various improvements in using libraries variables
* CMake: update and fix some bugs (#11, #13)
* parse dpaste:<code> syntax
