- Added data hash page to check integrity of compressed files.
- Fixed some minor bugs.

@demon964, deleting the BIN file during installation is a terrible idea.
However, you can modify your own script by editing "Resources\Includes\DSG\DSG_Module.iss" adding red text part.
But this will only work for BIN files contained on disks such as HDDs/SSDs and for non-splitted BIN files.

                if (not ISDoneError) and (not ISArcExtract(0, Arcs[I].Pct, CurrArc, Arcs[I].Output, '', Arcs[I].AType = tmArc, Arcs[I].Password, ExpandConstant('{tmp}\Arc.ini'), Arcs[I].Output, False)) then
                  ISDoneError := True
                else
                  DeleteFile(CurrArc);
