Subject: Separate C++ and python builds & make conda work nicely

- make builder (= advanced user or us ourselves) choose compilers
  and CUDA
- add a check for the C++11 flag for nvcc to work around the
  infamous boost bug if necessary
- use conda boost to build the C++ library
- simplify python bindings conda recipe to only build the bindings;
  the C++ library is now a build and runtime dependency
- add runtime dependencies to python bindings recipe
- some small adjustments to builder.py
