Bump up to v0.8.3

Introduce CI workflow based on GitHub Actions (#114 )
This introduces GitHub CI which runs builds and tests in a matrix configuration. It also changes the systemd repo to stable one. And puts the CI badge (plus a few more badges) to the README page. Fixes #44

 sdbus-c++ is a high-level C++ D-Bus library for Linux designed to provide expressive, easy-to-use API in modern C++. It adds another layer of abstraction on top of sd-bus, a nice, fresh C D-Bus implementation by systemd.

 sdbus-c++ has been written primarily as a replacement of dbus-c++, which currently suffers from a number of (unresolved) bugs, concurrency issues and inherent design complexities and limitations. sdbus-c++ has learned from dbus-c++ and has chosen a different path, a path of simple yet powerful design that is intuitive and friendly to the user and inherently free of those bugs.

 sdbus-c++ is a C++ D-Bus library built on top of [sd-bus](http://0pointer.net/blog/the-new-sd-bus-api-of-systemd.html), a lightweight D-Bus client library implemented within [systemd](https://github.com/systemd/systemd) project. It provides D-Bus functionality on a higher level of abstraction, trying to employ C++ type system to shift as much work as possible from the developer to the compiler.

-sdbus-c++ does not cover the entire sd-bus API, but provides tools for implementing the most common functionality - RPC method calls, signals and properties. There is room for additions and improvements, as needed and when needed.
+Although sdbus-c++ covers most of sd-bus API, it does not (yet) fully cover every sd-bus API detail. The focus is put on the most widely used functionality: D-Bus connections, object, proxies, synchronous and asynchronous method calls, signals, and properties. If you are missing a desired functionality, you are welcome to submit an issue, or, best, to contribute to sdbus-c++ by submitting a pull request.

Jan Kundrát	0d010440c5	Fix build with clang 9.0.1 and libcxx This should not be required in C++17 because there is an appropriate class template deduction rule [1] which infers that it's going to be a weak_ptr<T> when constructing from a shared_ptr<T>. However, in clang/LLVM's libcxx C++ STL implementation this only got implemented in May 2020 [2].
