Add clientid/username/password to MQTT nodes

Browse Source 
Alternative implementation, closes #42

The username/password as not stored in the main flow file for security reasons;
they are stored in the adjacent credentials file. This does mean an extra step
to importing an MQTT node, as the user has to manually edit it to re-add username
and password if needed.
