Noneo->Noneo

* Remove unneeded __futures__ imports

No longer needed with Python 2 support dropped.

* Remove unused utils.clean_object_caches func

Sounds like this used to have a purpose but no longer does.

* Remove py3.6 handler for ModuleImportError

We require 3.7+ now, no need.

* Clean up utils gc/sys imports

Move to top and import the modules instead of funcs from them.
Keeps the scope cleaner.

* Remove uses of the 'future' py2->3 module

This is no longer needed, now that we are Py3.7+ only. One
layer of indirection removed, and one less dependency.

* Condense requirements files down to one

PEP 508 defines a way to specify platform-specific requirements.
Rather than having to manage two different requirements files, let's
crunch them down to one and use that facility.

For more details on how this works, see:
https://www.python.org/dev/peps/pep-0508/

* Bump min Django version to 2.2.5

Bug fix release. For more details, see:
https://docs.djangoproject.com/en/2.2/releases/2.2.5/

* Messed up the merge; now removed win-req file

* Fix MSSP connect traceback. Resolve evennia#1930. Also add mock external_discord_hello inputfunc for Mudlet.

* Remove pillow from requirements

This was originally suggested due to an imagefield, but that is
no longer present. Since Pillow is not required to run Evennia,
we should remove it and let the users opt into it if they end
up wanting/needing it for their custom code.

* Refactor mod_import to use importlib

Switch from the deprecated imp to importlib. Also add tests and
clean up logic flow. This should be quite a bit faster than the
old implementation as well.

* Switch to module imports for importlib in utils

The present day guidance is to lean towards module imports for the
stdlib modules. Switch importlib imports to this instead of
plucking out the functions that we need. This makes it more
immediately apparent as to where the functions are coming from
in the application logic.

* Remove builtins imports

This module is not intended to be used directly in most cases, per:
https://docs.python.org/3/library/builtins.html

None of our usages warrant the explicit import. We also avoid some
confusion as folks dig to see what we are doing to require
importing builtins directly.

* Remove a couple of lingering u strings

These are not needed in Python 3.

* Update changelog with removal of pillow lib requirement

* Add auto-formatting via black

Introduce black, a Python code formatter. Also a Makefile that
includes two common targets:

* fmt (auto-format the code)
* lint (lint the code and return non-zero if out of spec)

We can re-use the latter in CI.

By introducing a code formatter, we can cut down on stylistic
variations across a now-large codebase. We can also avoid most style
discussions in PR if we just have this thing enforce it for us.
