wildcards

related to #29

This MR is a workaround for #29. It will check for wildcards in the basename of a list path and only concat dirname. If the dirname contains a wildcard, the concat path is removed completely since slk list output is ambigious in that case and the result directory can not be recovered from what slk returns.

I would still leave that #29 open since this MR not totally resovles this.
