Update 'Installer.sh'

Set Test all but one variables to =no.
Added test variable that times the installer in order to measure performance gains.
Added change to Governer when installer starts, to speed up a little Governer is set to Performce for the duration of the install.
Changed NodeRed installation behaviour to remove Clear in their script for debugging purposes.
Removed Domoticz dialog to choose the correct option (update or reconfigure), this is deprecated since Domoticz now installs unattended.
Added custom backgrounds for all other Domoticz themes that support backgrounds when the user Jarno is detected.
Deleted libx11 from the deinstallation list, this was causing conflicts with Nginx when trying to Remove or Autoremove.
