venv creation broken on Windows with spaces in python path

Start with hooks/post_gen_project.py lines 61-65 and reproduce the venv creation command using the reported Windows Python path containing spaces. Check the remaining calls in post_gen_project.py after venv creation, and consider the issue complete when project generation succeeds without manually rerunning the commands.

These lines to generate the virtual environment didn't work on my machine.

My python.exe is at c:\program files\python37\python.exe. Here's the error I get:

        venv creation failed.
        Make sure you have installed virtualenv on Python 2.

ERROR: Stopping generation because post_gen_project hook script didn't exit successfully
Hook script failed (exit status: 1)

I worked around this by running the venv commands and remaining calls in post_gen_project.py manually, but it'd be better if it worked.

Looks like #23 is a similar but much older issue.
