.gitignore is renamed to .npmignore, see http://stackoverflow.com/questions/24942161/does-npm-ignore-files-listed-in-gitignore

I tried put a empty .npmignore on both root and generators/app/templates dir, none is worked. generators/app/templates/.gitignore is still renamed to .npmignore after npm install
