0.9.0

This release adds a couple of simplified deployment options:

1. Simplfied CloudFormation stack without a deployment pipeline.
   It uses CodeBuild to create the config files and to deploy directly
   to S3.
   This mode is the new default of the CloudFormation setup so if
   you want to keep using the deployment pipeline setup (CodeCommit,
   CodeBuild, CodePipeline), you are going to need to explicitly set the
   CreatePipeline parameter to true.
2. AWS Mobile Hub project file that deploys the Web UI to S3 fronted
   by a CloudFront distribution. The Mobile Hub project also creates the
   Cognito Identity Pool, Lex Bot and IAM Roles. This allows to deploy the
   application from a single file hosted in github.

NOTE: At this point, there is a Content-Type issue with the files
deployed using the Mobile Hub project file. The Mobile Hub deployed
files seem to have its content-type set to octect-stream which causes the
browser to download the files instead of rendering. To work around this
issue, you can re-upload the files using the S3 console or aws cli. The
Makefile in the root dir can be used to upload the files with the right
content type. Use the command: make sync-website (requires setting
the bucket name with the WEBAPP_BUCKET environmental variable). This
issue will be further investigated.

Added

• Added Mobile Hub deployment
• Added new CloudFormation template codebuild.yaml used to deploy the
  application without a pipeline
• Added CreatePipeline parameter to the master.yaml template to control
  whether the stack should create a deployment pipeline
• Added build-time support to set web UI config fields that are commonly
  changed using environmental variables. This is in preparation to set
  these variables from CloudFormation parameters. The new variables include:
  • BOT_INITIAL_TEXT
  • BOT_INITIAL_SPEECH
  • UI_TOOLBAR_TITLE
  • UI_TOOLBAR_LOGO
• Added a new config directory in the root of the repo that includes
  build configuration
• Added a new src directory in the root of the repo to hold the
  website files. This includes a modified version of the iframe parent
  page and bot-loader that resides in the lex-web-ui/static/iframe
  directory. Eventualy, this new version should replace, somehow get
  merged with the other, or sourced in both places from a single file.
• Added a server.js file for quick development and testing. It loads
  the sample page from the dist and source directories. It can be used
  with the command npm start from the root directory. You may need to put
  the right values in the config files under src/config to make it work.
• Added CloudFormation format statement to all templates files
• Added .npmignore file
• Added sample code on how to use the Vue plugin for including the
  component into an existing Vue application

Changed

• [BREAKING] CloudFormation setup now defaults to not creating a
  development pipeline and just copy the prebuilt files to an S3 bucket.
  To use the pipeline, you now have to set the CreatePipeline parameter
  to true
• Refactored the build scripts and Makefiles to have better separation
  of config and code. The config config used by the Makefiles now resides
  under: config/env.mk. Some of the names of the Makefile have changed so
  you may need to change your environment if you were using the Makefiles
  from other script.
• The update-lex-web-ui-config.js build script now takes its config from
  a node js module in the config directory. The config is driven by the
  BUILD_TYPE environmental variable which controls whether the deployment
  is building the app from full source or using the dist dir. For this, the
  value of the BUILD_TYPE variable can be set to either full or dist.
• Updated CodeBuild environment to node js v6.3.1 using ubuntu
• Renamed iframe bot.css to bot-loader.css
• Updated dependency versions
• Clarified READMEs
