Support for anaconda/miniconda environments

[cpaulik]

Anaconda or miniconda environments are not listed in the pyenv versions command but in pyenv virtualenvs --list. The also must be activated using the pyenv activate command.

Could you add support for these kinds of environments? I could also help with the implementation if you tell me how you think the selection process should be.

Thanks for info. I need some time to think of it (say a day).

I had some time on my hands so I tried to fix this.
