Enhance event.linkTo() to use variables from another scope

[cfgrok]

Proposed Method Signature:

Event.linkTo( eventName:String, listOfKeysToAppend:string [, anchor:string] [, preferredContext:struct] )

Proposed Argument Descriptions:

1. eventName: The name of the Model Glue event to use, this will be the value of whatever is defined for EventValue in the modelglue.modelGlueConfiguration bean definition.
2. listOfKeysToAppend: A comma delimited list of keys that will be used as ordered URL parameters
3. anchor: An anchor to append to the URL string
4. preferredContext: a struct or something with public properties to use as a context for the items in listOfKeysToAppend. If a list item is not defined in preferredContext, or if preferredContext is not passed as an argument, the EventContext ( event.getValue() ) will be used to find the value. Note: Usage of the preferredContext argument will ensure not to alter the state of EventContext.

Proposed Usage:

event.setValue("WhiskeyPreference", 1)
event.setValue("CigarPreference", 1)

Event.linkTo("CashMoney", "AccountNumber,WhiskeyPreference,CigarPreference", "profilePic", { AccountNumber=123456789, CigarPreference=0 } )

The resulting link would be:

http://whatever.com?event=CashMoney&AccountNumber=123456789&WhiskeyPreference=1&CigarPreference=0#profilePic
