0030692: Data Exchange - introduce base framework RWMesh for importing mesh data formats into XDE document

Browse Source 
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.
