Un-vendor Pew

[uranusjr]

I believe we have removed all Pew usages in the code base.

• pewtwo entry point is deleted.
• Removed a related test. It was already skipped.
• Module pipenv.pew is removed.
• Vendored pipenv.vendor.pew is removed.
• Removed Pew from vendoring scripts.
• Removed patches for Pew.
• Comments and documentation is checked to rewrite Pew mentions to relevant virtualenv wording.

Does this cover project creation?

If this passes and covers project creation I’m good with it.

[techalchemy]

I.e pew new --project

[uranusjr]

Yes it does!

# Associate project directory with the environment.
# This mimics Pew's "setproject".
project_file_name = os.path.join(project.virtualenv_location, '.project')
with open(project_file_name, 'w') as f:
    f.write(fs_str(project.project_directory))

pew new --project == pew new + pew setproject.

p.s. We have test for project creation.
