The `buildPython*` function computes name from `pname` and `version`.
This change removes `name` attribute from all expressions in
`pkgs/development/python-modules`.
While at it, some other minor changes were made as well, such as
replacing `fetchurl` calls with `fetchPypi`.
* bemenu: init at 2017-02-14
* velox: 2015-11-03 -> 2017-07-04
* orbment, velox: don't expose subprojects
the development of orbment and velox got stuck
their subprojects (bemenu, dmenu-wayland, st-wayland) don't work correctly outside of parent projects
so hide them to not confuse people
swc and wld libraries are unpopular and unlike wlc are not used by anything except velox
* pythonPackages.pydbus: init at 0.6.0
* way-cooler: 0.5.2 -> 0.6.2
* nixos/way-cooler: add module
* dconf module: use for wayland
non-invasive approach for #31293
see discussion at #32210
* sway: embed LD_LIBRARY_PATH for #32755
* way-cooler: switch from buildRustPackage to buildRustCrate #31150
