patch for Korean IME

[Sang-Min Yoon]

While inputing Korean string, intermediate characters must be shown on
the cursor.

( '' -> key press r -> 'ㄱ' -> key press k -> '가' -> key press r ->
'각' -> any key -> '각' is inserted )

But the current Scintilla does not show intermediate characters, but
the result character.
And the default IME window that shows intermediate characters is
appeared out of the application window. (left-top of the screen)

So I made a patch for this problem.
It checks the input locale, so it does not affect other environments.

OK. The patch will be applied after 1.75 is released.

This is how the IME is supposed to work according to Microsoft
documentation with intermediate characters shown in the composition
window and only GCS_RESULTSTR text going into the document.

The initial window is outside Scintilla but typing further
characters places the IME window next to the caret.

The Japanese IME shows the composition window at the correct place
in Scintilla.
