"make clean" should remove virtualenv directories

[craigmaloney]

Ran into an issue with an old install that might have been avoided with a newer virtualenv install. When I set up a LXC container to point to my old Bookie directory it got into a state where pip was having importing things. Had "make clean" removed the virtualenv directories it would have reinstalled everything from scratch.

Or perhaps a "reallyclean" option could be added to run both "make clean" and also remove the virtualenv directories?

Just a thought.

And "make clean_all" does that, and handily already exists. Eventually I'll remember this. :)
