Missing IrisRestApiClient

There are some externals in the webpack config that aren't included in the repo anywhere, nor documented so far as I can tell:

gateway-cordova/webpack.config.js

Lines 80 to 83 in 161cced

    
           externals: { 
        
           	'aws-wrapper': 'awsWrapper', 
        
           	'RestApi': 'IrisRestApiClient', 
        
           	'AWS': 'AWS',

It's this file: https://github.com/nRFCloud/gateway-cordova/blob/master/www/index.bundle.js

I've updated webpack.config.js to have a comment pointing to it.

	externals: {
	'aws-wrapper': 'awsWrapper',
	'RestApi': 'IrisRestApiClient',
	'AWS': 'AWS',
