ScriptQuery mapping

[Mpdreamz]

See: #1944

We currently map script query as a single unit but we need to move the inline, file and id properties under another script property of type ScriptBlock.

This ScriptBlock should be used under ScriptScoreFunction rather then the whole ScriptQuery

We have IScript which we use everywhere a script can be specified. Can we use that instead?
