• Reverts 1c49398, which was erroneous in that it didn't consider the fact that we use npmignore to copy a new gitignore as part of lineman new. gitignore has no defaults, so it's necessary to include them in the npmignore. The mistake was probably made because of a failure realize that we're forced to generate the gitignore file, because npm itself will (no matter what we do) strip out any gitignore files from what we publish to npm.
