TSynBaseCompletionProposalForm.CreateWnd Bug

[ErwinDenissen]

SetWindowLong in TSynBaseCompletionProposalForm.CreateWnd should use IntPtr, otherwise it can cause an AV in x64.
SetWindowLong(Handle, GWL_WNDPROC, IntPtr(GetWindowLong(Handle, GWL_WNDPROC)));

Not sure if that code is even still required and/or correct.

On a side note Integer is also used in a couple of other places (in SynEdit.pas), but that is inside {$IFNDEF UNICODE}.

SetWindowLong is not called under 64bit. However, the component still crashes at startup.
EAccessViolation with message 'Access violation at address FFFFFFF2F80F84. Execution of address FFFFFFF2F80F84'.
