Add npm support for local GH Url support

* Add basic package.json so npm can access using NPM styled GitHub url... mirror bower info
* Fix link in `bower.json` to be secure
* Add `.gitignore` so push doesn't send those files from `node_modules` and one other mentioned in `bower.json`

**NOTE**: Currently skipped version bump and tag because I don't know how this is managed for this repository with the generation of the fonts

Thank you for the consideration and nice work with the icons.
Correct homepage to the right url in package.json
