0024023: Revamp the OCCT Handle -- general

Missing headers added; includes of headers "Handle_...hxx" removed.

Misuses of macro Handle() and its use in typedefs corrected.

Alias classes Profile and Option are removed from IFSelect; ones defined in MoniTool are used directly.

Removed header files defining only Handle classes (except Image_PixMap_Handle.hxx)

Classes SelectMgr_BaseFrustum and now inherit Standard_Transient and can be manipulated by Handle (not NCollection_Handle)

Fixed reference-type local variable pointing to temporary object

Use of handle in conditional expressions and comparisons to NULL are replaced by call to method IsNull()
