Get Filenames step ignores parameter values

When using the "Get Filenames" step with a parameter (for either the directory or wildcard fields), the step ignores any custom value that the user sets for the parameter when running in Spoon, and instead uses the default value. All other steps appear to get the custom value correctly, it is limited in this case to the "Get Filenames" step.

In reviewing the "Get Filenames" step, we pass in a "TransMeta" variable space, which uses the default parameter values, instead of passing in the Trans or Step object itself, which will contain the updated variables and parameters that are set at runtime, as is common practice in other steps.
