[WIP] Cordova app support

[ghys]

Add the Quasar cordova mode.

Add support for a baseUrl and credentials and a form to "login" to openHAB when the connection is not configured (or down).

Demo (for iOS, Android works similarly):

I don't have an Apple developer account so I can't provide binaries to test, here are some notes on how to build it for yourself:

• Install node (for instance with homebrew): brew install node
• Fetch this branch
  • git clone https://github.com/ghys/habot
  • cd habot
  • git checkout -tb cordova
  • git fetch
• cd web
• Install vue-cli and quasar-cli globally: npm install -g vue-cli quasar-cli
• Install dependencies: npm install
• mkdir src-cordova/www (temporary)
• Run the build: quasar build -m cordova -t ios -T ios
• If it went well, you'll have an Xcode workspace and project in src-cordova/platforms/ios
• Follow these instructions to deploy the app on your own device: https://stackoverflow.com/questions/43932076/how-to-build-app-on-iphone-physical-device-without-developer-account
