Fixed ios and android files

Fixed #86 and #87

• With Android, user might have to open android folder with Android Studio in order to get the app running

Moved template to another repo and instead of reimplementing the cli, using the template functionality from react-native-cli to create the project.

Added React Router option -r, --router So users can add -r or --router option to the cli command like this:

npx crnwa -r myApp

• fixed fast refresh #76 and debugging option by commenting out @babel/plugin-proposal-class-properties from babel config
• fixed adding .gitignore file to template
• added .prettierrc.js file to the root project
• silenced rename command to not log to stdout

added package crnwa fo users can run npx crnwa appName

Fixed npm run android issue

Changed copy files strategy like in the react native cli

Updated react, react-native and react native web versions and created a new template from the react-native cli and create-react-app

upgraded react-native-web version

Added react-native-rename to rename the project before installing dependencies #37
