Title: Use env.virtualenv if directory is not specified.

When you use the same virtualenv over and over it's best to specify its directory once.
Fabric provide the ``env`` singleton to store such variables.

I modified the `python.virtualenv()` method to look at the `env.virtualenv` attribute if `directory` is not specified.

An exception is raised if none is provided.
