Sliders fire OSC messages when the value gets updated from the server

[SolfaMode]

Steps to reproduce:
Given a slider with OSC address X.
Update the float value of X in the OSC Query server and send it using Web Socket.

Expected result:
Javascript updates the slider and done

What happens:
oscqueryhtml additionally sends a new value for X back to the server.
This can produce an infinite update-cycle.

Workaround:
In index.js applyOSCMessageValue() set a global flag before targetElem.rangeSlider.update({value: value}, false);
Clean that flag after the call.
In userinput.js controlEvent(e) avoid sending value if flag is set.
