Refactored ValueInjector for other projects.
Post processed HTML with htmlTemplate parameter

New submission paramater value 'htmlTemplate:some-page.html'
DataDoc will be injected into html placeholders before html posted
to webservice. The target service could send emails or create PDFs?
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.
Test for value injection using attribute XPath
Submission option messageOnHttpError

This includes connection timeouts.

Support for text/plain submission responses.
Cause still logged when using custom error message

FlowException now has frontendMessage property in addition to message.
Message is logged and frontendMessage is sent to the browser.
RemoteSubmissionHelperException now extends FlowException so doesn't have to be wrapped.
