Title: Updated lockfile message for "composer install" command

The behaviour of the lockfile was a little confusing to me. I assumed if I added a new dependency I should run 'composer install' again. It was not immediately obvious from the output of the install command what was going on and I was confused why my new package had not been installed.

I understand that a better fix would be to compare composer.json to the lockfile, but until that has been implemented this will maybe help some newbies out.
