Emulate GNU Autotools make check

 - Fixes #103
 - Provide `check` target that will build tests
 - Tests are no longer included in the `all` target
 - `make check` will build in parallel: the static and dynamic library,
   all tests and run them with `ctest`
 - `make` will build the library and documentation if enabled
