0.8.0

This release makes it easier to include the chatbot UI into existing
sites. The project now distributes a pre-built library in the dist
directory. This allows to use the chatbot UI without having to build the
application. The root directory of the repo now contains a package.json
file to make it easier to npm install it.

There are a few breaking changes regarding the supported URL parameters
which now use the lexWebUi prefix to avoid conflicts when including
the component in an existing site.

Changed

• [BREAKING] Changed config passing URL query parameter from config
  to lexWebUiConfig
• [BREAKING] Changed URL query parameter to run in embedded mode from
  embed to lexWebUiEmbed
• The parentOrigin config variable now defaults to
  window.location.origin to support single origin iframe setups
  without having to set it in the the JSON config file
• Restructured Vuex store including:
  • Split state, mutations and actions to individual files
  • Moved audio, recorder, aws credentials/clients out of the state.
    Those now exist as module variables visible from the store actions
  • AWS credentials from parent are now manually recreated to avoid
    including the AWS SDK as part of the store
• Changed from using vuex mapGetter in components to instead use the
  store state variables. This was done to avoid redistributing vuex
  in the built library and to support vuex being loaded outside of the
  chatbot ui.
• Moved Vue component initialization from LexApp.vue to LexWeb.vue
• Moved Page component to LexApp.vue from LexWeb.vue
• Moved webpack related import config from recorder to the general
  webpack config
• Commented out webrtc-adapter import in preparation to deprecating it
• Changed constructor arguments of lex client to accept a
  lexRuntime client instead of AWS credentials or SDK config. This allows
  redistributing without having to include AWS SDK as a direct dependency
• Changed iframe container class name
• Rearranged the README files. The main README contains info about the
  npm package and instructions to use the library. The CloudFormation and
  application details where move to different README files.

Added

• Created a Vue plugin that can be used to instantiate the chatbot ui
  both as an import in a webpack based project or by directly sourcing
  the library in a script tag. The plugin registers itself and adds
  a property named $lexWebUi to the Vue class. It adds a global Vue
  component name LexWebUi
• Added a distribution build config and related scripts
• Added an example on how to encode the URL query parameter config
• Added a new config object key urlQueryParams holding the url query
  parameters
