virtualenv tool allows to set alternative prompt prefix, Python's venv module should allow this too.

Basically, this allows one to run:

python -mvenv --prompt Quux myenv

And see "(Quux)" as a prefix after environment activation (instead of the "myenv" in this case).

Based on the patch of Łukasz, I have updated it to the last revision of Python 3.5a3 (today, 16th April)

stephane@sg1 ~/p/c/bin> ./python3.5 --version
Python 3.5.0a3+
stephane@sg1 ~/p/c/bin> ./python3.5
Python 3.5.0a3+ (default:c969413584cf+, Apr 16 2015, 15:17:46)

I tested the patch, this one works fine and the prompt is really changed if we specify it on the command line of -m venv

Thanks! The patch looks good to me. Some review comments: http://bugs.python.org/review/22829/

ok, I will propose an update with the comments of the review.
