`skpm link` should autodetect local plugin?
I spent a few minutes trying to find out the right path argument for `skpm link`. I think it would be nice if it autodetected that it's being run in a plugin development folder, and do the right thing automatically (i.e: make `skpm link` do a `skpm link .` under the hood if you run it on a project folder).

Apologies in advance if I'm not making myself very clear, coffee hasn't kicked in yet : )
