Client: Minor visual things - layout etc

[mitra42]

The client is ugly ! Its purely functional at the moment, until there is some serious CSS skills available to make it look good, here is a place to not minor items that need fixing.

• Spacing in MqttWrapper
• Wrapper should show organization name, not abbreviation.
• Display of mqtt-client at top
  • maybe a MQTT light green/yellow/red with an "i" for information
  • information should give server name and textual status
• Project should show name, not topic
