Marcus Boyd 088ae2c920 python3Packages.spyder-kernels: Add spyder-kernels_0_5 ...

Previously top-level/python-packages.nix called spyder-kernels v0.5 for
Py2k. Now both v0.5 and v1.8 (default.nix) are in pythonPackages, as
required by cq-editor and spyder v4 respectively.
v0.5 also now comes from GitHub instead of PyPi, with checks enabled.
