Remove python 2.7

[ChadBailey]

Removes all instances of and references Python 2.7 from the codebase as well as cookiecutter.

Fixes #405 - Python 2.7 is end of life in less than 60 days.

Also adds .vscode to .gitignore, fixes broken test in win32, and resolves all flake8 linting errors

Tip: https://github.com/asottile/pyupgrade can find and autoupgrade lots of Python syntax to Python 3+:

pip install -U pyupgrade
pyupgrade `git ls-tree -r HEAD --name-only | grep ".py$"` --py3-plus

Tip: These statements all evaluate to True and can be simplified:

tests/test_bake_project.py:if sys.version_info > (3, 0):
tests/test_bake_project.py:    if sys.version_info >= (3, 5):
tests/test_bake_project.py:    elif sys.version_info >= (3, 3):
tests/test_bake_project.py:    if sys.version_info >= (3, 5):
tests/test_bake_project.py:    elif sys.version_info >= (3, 3):

Updating these tests weren't a part of my contribution, I was only refactoring to fix the linting errors. While looking through the tests, I do think they could use a refresh though... perhaps it should be done as a separate effort

I don't understand the context here, can you elaborate?

edit: nevermind, I think I figured it out... you're just making general recommendations for migrating from python2 to python3 right? I looked for code that was specifically designed to backport to python2 and didn't see any but I may have missed something

Hi! I thought these could be updated as they're things that can be done to modernise and simplify the codebase for #405, but I'm happy to make another PR for them.

pyupgrade automatically removes and upgrades code that is only needed for Python 2.

Looks good, could also add this Trove classifier to both setups:

Programming Language :: Python :: 3 :: Only

Please see PR #545.

You're right, looking at your PR I did overlook some stuff that could have been updated. Thanks for taking the effort to do that!

Good call out, I'll update the PR with this when I return from work
