(PICT): fixed 16bpp images. (GDT): added image format. (DXR): tweaks to recognizing DXR inside exe files. (NSA): recognize mp3 files named as nsa. (TLZ): added ContainedFormats. (WrapSingleFileAchive): class that represents single file as an archive. (DesertCgOPener): Software House Parsley archive. (Triangle.RleReader): utilize UnpackV2, replaced BinaryReader with IBinaryStream.
