Wildcarded path fix
- Fix an issue when a wildcarded application name returns no results (this facility is used in the ResApps section of PreDesktop, but was masked in testing by an IfThere on an absent directory)
- When handling paths, hold the original path internally, avoiding a potential 'Dir not found' error from OS_GBPB. The name gets canonicalised when formulating the ResourceFS entry so no need to canonicalise it early.
