This pull request is dependent on Antranig's pull request that fixes : https://github.com/fluid-project/infusion/pull/581

I've started working on this in the branch: https://github.com/cindyli/infusion/tree/FLUID-5552

Most pieces are back working except one last issue. To produce:

1. Open examples/framework/preferences/conditionalAdjusters-singlePanel/ in a browser where a debugger is turned on;
2. Turn on "speak text" preference, adjust the slider for "Words-per-min", click on "reset" button;
3. This javascript error occurs:

ASSERTION FAILED: Cannot resolve reference {change}.value from component { typeName: "fluid.textfieldSlider.textfield" gradeNames: ["fluid.textfieldSlider.textfield","fluid.viewRelayComponent","fluid.commonViewComponent","fluid.standardRelayComponent","fluid.modelRelayComponent","fluid.commonModelComponent"] id: byh4wskj-1519} which has been destroyed

The error doesn't occur if "Words-per-min" and other prefs in conditional panels have never been adjusted.

The same issue can be produced with all conditional panel examples.

Clicking on the reset button triggers:
1. Reset the central model to the default which resets "speak text" to false and "words-per-min" to its original value. This should also triggers the model relay for the "Words-per-min" prefs value to be relayed to "Words-per-min" text field slider;
2. Resetting "speak text" prefs to false results in the destroy of its conditional panels including the "words-per-min" text field slider. A refreshView() is called right after the destroy to stop showing these conditional panels - https://github.com/cindyli/infusion/blob/FLUID-5552/src/framework/preferences/js/Panels.js#L334-L340

The debugging log shows the destroy of the "words-per-min" text field slider (line 337) happens before the error occurs. So it seems even though the text field slider should have been destroyed, the model relay onto it continues to happen.

Note the upgrading the video player ( VP-295 ) with the new modelRelay system can't go ahead without ("global instantiators")
