MQTT Password param blank in config page and saved as empty
I've been testing the IotWebConf06MqttApp example and I notice that when accessing the config page, the AP & WiFi password fields are shown as empty (to hide the current password) and if you leave them empty and click apply it just re-uses the current passwords but the Mqtt password is also shown as empty but if you leave it empty and click apply it saves a blank password. How can I make the Mqtt password parameter work like the AP & WiFi password params?
All password behave the same: updates the value when change provided. There were some changes in v3.0.0 in the parameter handling, please verify any problems against this version!
Feature request: It would be nice to have those fields show the text *** just so everyone can be sure that they already contain values when saving.
