Implement IME menu

Our IMM32!ImmGetImeMenuItems function is not implemented correctly yet.
This function provides IME menu for Windows internat.exe or our kbswitch.exe.

NOTE: ImmGetImeMenuItems is deprecated and not available in Cicero.

EDIT:

Even on WinXP Japanese, after ctfmon.exe terminated, Win2k indicdll.dll and internat.exe can display the IME menus: WinXP-JPN-after-ctfmon.exe-killed-and-use-2k-indicdll.dll-and-internat.exe.png
