auto select resource "updater32/64.RES" by build type win32/64 during build

I suggest to change heidisql.dpr to automatically select the resource accoring build type win32/64. Benefit is not to rename manually updater32/64 to updater before building win32 or win64.

old

{$R ..\..\res\updater.RES}

new

{$IFDEF Win32}
{$R ..\..\res\updater32.RES}
{$ENDIF}
{$IFDEF Win64}
{$R ..\..\res\updater64.RES}
{$ENDIF}
