project.el users are an unknowable bunch, so far. This change is 
unlikely to break anything, it just might make using project commands 
more "magical", possibly not in a good way. Let's just wait for feedback.

The other options I had: temporary, and simple. But I wanted to 
emphasize the fact that the user will be asked for the project's 
directory every time they'll try to use a project-related command.

Anyway, you're welcome to change the name, retouch the newly updated 
docstring, etc.

Done, and closing.
