Change the standard icons for all switch types

[DosN]

For some switch types, like "motion sensor" i cannot changed the icon.
When i define the swtich type ON/OFF , i can add easily a custom icon. But then the function is different , i do not want a motion sensor which has a ON/OFF function.

It would be nice to changed all the icons it a new version of Domoticz?
To changed the icons in the directory www.... on the server is actually not the way ( will be changed again when upgrade the software i think)
