        * X11Structs.cs : added couple of structs for XIM support.
        * X11Keyboard.cs : release XIM in case it failed to create XIC.
          Use consts for XNblah string.
          Add support for IM style customization and (not-yet-working)
          XIC creation for preedit-position and preedit-callback.
          Right now use MONO_WINFORMS_XIM_STYLE environment variable
          (list of: over-the-spot | on-the-spot | root). I'm still
          looking for the reason why those preedit modes don't work.
