fix handling of virtualenv in deploy

The previous version had these lines:

    VIRTUAL_ENV=${VIRTUAL_ENV:-"$SUPPORTDIR/virtualenv"}
    source "$VIRTUAL_ENV/bin/activate"

...which made too easy to inadvertently run deploy under an inappropriate
virtual env.  The current version replaces the two lines above with

    VENV=${VENV:-"$SUPPORTDIR/virtualenv"}
    source "$VENV/bin/activate"

...so that the virtual env used by deploy can still be overridden explicitly at
the command line, but there's much less risk of doing this overriding
inadvertently (through the current environment).
