TH function to list names in scope
I [asked about this on stackoverflow](http://stackoverflow.com/questions/26394199/using-templatehaskell-to-list-all-names-in-a-namespace), and apparently it doesn't exist yet.
I want a TemplateHaskell function variablesInScope :: Q [Name] that returns a list of the Name's of all the variables in scope. TemplateHaskell obviously has this information available in order to implement functions like reify :: Name -> Q Info and lookupValueName :: String -> Q (Maybe Name). So it seems like this might be a pretty simple function to add.
