Add setup.py command to do a full in-place build

[esc24]

It is convenient as a developer to do in place builds. Previously this meant calling python setup.py build_ext --inplace. However, one now needs to build the standard names file and it would be good to be able to trigger the pyke rules compilation in a similar way to the out of place build.

Implement a new setup.py command called build_inplace (or a better name if you can think of one) that does the equivalent of:

1. python setup.py build_ext --inplace
2. python setup.py std_names
3. python setup.py pyke_rules (see Safely build PyKE rule base. #435)

Note you must be able to pass the -I, -L -R options (and their equivalents) though to the build_ext command, and --with-unpack must work.

The standard approach of pip install -e . has become ubiquitous.
What is missing is the fact that we have some bespoke commands that one must remember to do. I'd like them to be rolled into the standard build.

Did #2891 address this?

Did #2891 address this?

I believe that pip install -e . now works, so I guess "yes".

I checked this : it runs python setup.py develop, which correctly generates pyke rules and std_names.py 👍

Thanks for highlighting @rcomer !
