RWMesh_CafReader - added new interface class for common workflow for reading mesh data files into XDE document. OSD_Path - added auxiliary methods splitting path into folder+file pair and checking relative/absolute path semantically: OSD_Path::FolderAndFileFromPath(), ::IsRelativePath(), ::IsAbsolutePath(). V3d_TypeOfOrientation enumeration has been extended with aliases (like front/left) for Z-up and Y-up conventions. V3d_View::SetProj() now accepts argument for asking Y-up instead of Z-up. Added command vviewproj defining standard camera direction. Commands vaxo, vleft, vright, vtop, vbottom, vfront, vbottom now redirect to vviewproj. TCollection_AsciiString::SubString() now uses Standard_OutOfRange_Always_Raise_if() to suppress GCC warning. Eliminated gcc 4.4 compilation errors within Standard_OutOfRange_Raise_if,Standard_RangeError_Raise_if.
