Werk #5920: Windows: use standard file matching patterns for fileinfo

Until now, Windows agent was using a non-standard way of defining recursive wildcards. From now on, the supported wildcard patterns '', '?' and '' work in a standardized way. Recursive patterns can be defined with '', matching all descendants of the path so far. Previous patterns with single ''s on several directory levels will from now on work as non-recursive patterns conforming to the standard.
