Add support for storing the registry in a project folder

Currently we have 2 options for registry location:

1. In a global per user location
2. In a virtual environment root directory

When running inside a virtual environment, the global per user location is not checked since the registry contains settings that typically should not be shared among virtual environments (like what components are checked out locally for development vs have production versions pip installed).

It makes sense though to have a third option where users can create a project directory and if they are in that project directory the registry comes from there.

There will need to be a way to make clear what registry is being used so that people don't get confused about why things don't work when they switch directories.
