0027901: Resource_Manager creates directory with insufficient permissions

Resource_Manager now sets RWXD permissions for the created directories to allow their removal.
Method OSD_Directory::Build() will create intermediate directories if they do not exist yet.
OSD_FileNode is corrected to clean error status in method Exists().

Tests bugs fclasses bug181_1 and bug181_2 are corrected to check existence of generated resource files; TODO is removed in bug181_2.
