Title: Added PYTHONPATH support

Hi,

Some features (for example running python syntax checkers from [Syntastic](https://github.com/scrooloose/syntastic)) rely on the `$PYTHONPATH` environment variable which isn't currently being handled by `:VirtualEnvActivate`.

This pull request simply adds `$PYTHONPATH` support to this already very useful plugin!
