Update package.json for publishing to npm

address #2078

- removes private: true flag from package.json
- created .npmignore file and moved all of buildGlob
 file patterns into here, negating all patterns as
 the npmignore file defines what is to be excluded
 and not included.
- gruntfile now uses the inverse of the .npmignore file
 to define what files to include in a release

.npmignore
