FACES-1999 Render all component scripts within a single AUI().use() sand...

...box within ajax requests
@ngriffin7a,
It is necessary to remove the `ClientScript` instance from the `requestMap` here because if it is not removed, Liferay will pick it up and throw a `ClassCastException` when trying to turn it into `ScriptData` and render it. I was thinking that it might be better to store it in the `requestMap` with a different key than `WebKeys.AUI_SCRIPT_DATA` so that it wouldn't be picked up by Liferay. Then I don't think that we would have to remove it. Would that work? Would it be an improvement?
