feat: add npm support in main repository

[wesleycho]

• Add support for consuming the main repository via npm for releases

This addresses #4739.

This may still require a docs update - any recommendation for where to put that @Foxandxss ?

[wesleycho]

Hmm this is not quite right - need to define the ui.bootstrap module still.

[wesleycho]

My thoughts - we will want to document usage of this, as this is a major change.

There is no good way to bundle template support, but we can point people to some loaders such as https://github.com/teux/ng-cache-loader and https://github.com/WearyMonkey/ngtemplate-loader for Webpack and https://www.npmjs.com/package/browserify-ng-html2js for Browserify. We could perhaps provide a template.js helper file that does a bunch of requires for the templates, creates a ui.bootstrap.tpls module and export that, and import it into the index.js to maintain consistency with the previous complete bundle. This would require people are using Browserify or Webpack, and have the proper config setup for requiring HTML templates.

Edit: Hmm, looks like the different tools handle template bundling & loading differently. Maybe best to let the users use it however they desire and not do anything here except document it.

[Foxandxss]

Yeah, we have our hands a bit tied in regard of what we can provide. All we can do is to document the different options.

I will think in how can we make it as easy as possible.
