Configurable baseTopic

[manelmg]

Hi Marvin,
Great job with Homie ESP8266, it's really amazing.

I have seen that in node red, the configuration node has the base topic hardcoded as "devices/" ( this.baseTopic = 'devices/' + this.deviceId; in line 24).
I am asking if it is possible create a new configurable field to modify this property, so the default value in set up configuration (http://setup.homie-esp8266.marvinroger.fr) is "homie/". Or at least change default base topic in node red to be the same at in set up configuration page.

Thanks in advance,
MAnel
