Summary: Timer support for nsDialogs

Initial Comment:
Inspired by this thread: http://forums.winamp.com/showthread.php?s=&threadid=296985

I added timer support for nsDialogs. Patch adds two new functions to nsDialogs (CreateTimer and DestroyTimer).

nsDialogs::CreateTimer time_in_milliseconds function_address
On sucess it will push timer id and on failure "error" to the the stack. Timer id be also waiting on the stack when the callback function is called.

nsDialogs::DestroyTimer timer_id
Simply kills the timer specified by the timer id. Doesn't push anytin in the stack.

WM_TIMER notification fo DialogProc

    case WM_TIMER:
    {
      struct nsControl* ctl = &g_dialog.controls[wParam - 100];

      if (ctl == NULL)
        break;

      if (!ctl->callbacks.onClick)
        break;

      pushint((int) wParam);
      g_pluginParms->ExecuteCodeSegment(ctl->callbacks.onClick - 1, 0);
      break;
    }

CreateTimer and DestroyTimer functions

void __declspec(dllexport) CreateTimer(HWND hwndParent, int string_size, char *variables, stack_t **stacktop, extra_parameters *extra)
{
  nsFunction  callback;
  UINT time;
  size_t id;

  // get info from stack

  time = popint();

  if (!time)
  {
    popint(); // remove callback from stack
	pushstring("error");
    return;
  }
  
  callback = (nsFunction) popint();

  if (!callback)
  {
	pushstring("error");
    return;
  }

  // create item descriptor

  id = g_dialog.controlCount;
  g_dialog.controlCount++;
  g_dialog.controls = (struct nsControl*) HeapReAlloc(
    GetProcessHeap(),
    HEAP_ZERO_MEMORY,
    g_dialog.controls,
    g_dialog.controlCount * sizeof(struct nsControl));

  g_dialog.controls[id].type = NSCTL_UNKNOWN;

  // create timer

  SetTimer(
    g_dialog.hwDialog,
    (100 + id),
    time,
    NULL);
  
  g_dialog.controls[id].window = NULL;
  g_dialog.controls[id].callbacks.onClick = callback;

  // push back result

  pushint(100 + id);
}

void __declspec(dllexport) DestroyTimer(HWND hwndParent, int string_size, char *variables, stack_t **stacktop, extra_parameters *extra)
{
  UINT id;

  // get timer id from stack

  id = popint();

  // kill timer

  KillTimer(g_dialog.hwDialog, id);
}
