Remove amd files from the build

Users can utilize the UMD library if they are still using require.js and if they need to have specific modules, they can consume the cjs or es6 modules via webpack or similar.

-1. Why doesn't IE like the `default` name in the AMD module?
-
-  Some browsers such as particular versions of IE treat `default` as a reserved word in JavaScript source files. To safely use this you need to reference this via the `Handlebars['default']` lookup method. This is an unfortunate side effect of the shims necessary to backport the Handlebars ES6 code to all current browsers.
-
 1. How do I load the runtime library when using AMD?
 
-  There are two options for loading under AMD environments. The first is to use the `handlebars.runtime.amd.js` file. This may require a [path mapping](https://github.com/wycats/handlebars.js/blob/master/spec/amd-runtime.html#L31) as well as access via the `default` field.
-
-  The other option is to load the `handlebars.runtime.js` UMD build, which might not require path configuration and exposes the library as both the module root and the `default` field for compatibility. 
-
-  If not using ES6 transpilers or accessing submodules in the build the former option should be sufficient for most use cases.
+  The `handlebars.runtime.js` file includes a UMD build, which exposes the library as both the module root and the `default` field for compatibility.
