Added form id as a class on the parsed form.
Added rf.formid attribute to parsed form.
rf.suppressDebugBar works in same container

Flow option rf.disableInputsOnSubmit is now sent in each response not just after flow loading, so option will be preserved if multiple containers are used in the same flow.

Allowing action rf.suppressDebugBar option even when loading into the same container.
Fix: Reinstating flow id in debug bar href.
Submission param value injection using {{}} syntax
Fix: Validate between args parsing.
More correct hiding of excluded elements.

Now using a class to show/hide elements with rf.includeIf
rather than jQuery show()/hide(). This prevents
stylesheet-hidden elements being displayed.
Option csv can escape commas with a backslash
Massive performance fix using sealed shared scope.
