Decision Cards; Expose Public variables to intellisense in Rules

Any publicly declared variables before the Main function in a Decision Card's Script code can now be viewed when editing a Rule.

They will appear in the "Rule Conditions" intellisense and also in the "Rule Condition Builder", e.g.:

' Public Properties for Rules
Public MyClient As finClient
Public MyDetails As ISKeyValueList

Public Function Main(source As Object, decisionOutcome As finDecisionOutcome, questionType As String, questionId As String, parameters As ISKeyValueList) As Boolean
End Function
