EXTRAS-17 - Improve IDL behavior for wizard items when a variable of the wrong type is passed to set_metadata

[tclarke]

When the set_metadata command is called to change the value of a wizard value item, the type of the item is derived from the value passed by the user to the set_metadata command. If the type of this value does not match the type of the value item in the wizard, the returned error message, "unable to find item in wizard file", is not very helpful to the user.

When evaluating, consider at least the following options:

1. Add documentation to specifically enumerate the type conversions for set_metadata (this is useful because, e.g., IDL UINT maps to a C++ unsigned short and this can be confusing).
2. Improve the error message reported to say the type of the value passed in (e.g.: "unable to find item of type in wizard file").
3. Automatically cast the value to the appropriate type.
