When adding this library as embedded library with private
"target link", e.g. only used inside private source files, the
library does not need to be installed when the main project gets
installed.
This adds an additional option `JSON_Install` similar to the
test-build control switch in order to skip installing headers and
CMake config files if requested.
Avoids using
```cmake
add_subdirectory(path/to/nlohmann_json EXCLUDE_FROM_ALL)
```
which has further side-effects:

Takes an lvalue reference, and returns the same reference.
This allows non-default constructible types to be converted without
specializing adl_serializer.
This overload does not require CopyConstructible either.
Implements #1227
"Concepts" have been renamed to "named requirements".
This is because P0898R3 Standard Library Concepts has been merged into
C++20.
Cppreference have moved their links accordingly.
The README says:
> "The library itself contains of a single header file ..."
I guess "consists of a" is the wording that was intended here. Alternatively, "contains a" might also be what was intended. Either way, I think both versions work equally well and thus choose the one that I believe was intended.
I contributed a package to the Spack package manager.
Spack is a flexible package manager that supports multiple versions,
configurations, platforms, and compilers. It is popular in
high-performance computing.
Beside the fix discussed in #961, we also had to re-adjust a test case. It seems that it was failing before, and I "fixed" it to work with the broken implementation...
- updated documentation wrt. new repository layout
- temporarily switched off Homebrew --HEAD building (can only be switched on after release)
- set copyright date to 2018
