This reverts commit c4ab8f82.

I totally forgot about byte order marks in this scenario.

Change the definition of the operator override of reverse iterator to using the result of the base class directly

operator>> now works as expected.

Fixed to make sure no token is "overlooked".

Also added a Travis builder with -std=c++1z

fix doxygen error of basic_json::get()

Fixing assignement for iterator wrapper second, and adding unit test

Adding first and second properties to iteration_proxy_internal

Adding support for Meson.

Test cases succeed as expected, but the example in #367 is not fully
realized yet.
