Added check on directory in Local_Storage::file_exists

Browse source 
Added check on directory in Local_Storage::file_exists.
Added check in get_filenames_recursive if last char is the path separator (some use cases were adding a path separator even if there were already one).

In base.h, added check on s and r, that will avoid an out-of-range vector exception on Visual Studio, same for network.cpp.
