Custom Page Templates

fixes #1969

- creates new ./server/helpers/tempalte.js method
 which returns the correct view to use when rendering

- updates fronted controller to check if a custom page template
 exists and if so then uses that to render the static page

- adds additional class name to body_class helper when
 a custom page template is being rendered

- adds tests to address all new features
Update package.json for publishing to npm

address #2078

- removes private: true flag from package.json
- created .npmignore file and moved all of buildGlob

 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
