Add a "shell" command similar to the existing "global" and "local" commands, which sets the version in an environment variable instead of writing it to a file. This was inspired by the similar functionality in rbenv. It works by adding a wrapper function for the asdf command. It forwards to a "sh-shell" command that returns the exports as shell code which is then evaled by the wrapper. This is a little gross, but we need to run the code in the shell context in order to set variables. Resolves #378
