Meridiem Parser support for Korean

I found that almost of language datas can't support parse meridiem correctly now.
I made a fix and test case for Korean language data.


before this fix:

    // PM 2
    value = moment("오후 2시", "A h시", "ko").format("hh"); // => 02

with this fix:

    // PM 2
    value = moment("오후 2시", "A h시", "ko").format("hh"); // => 14
