Meridiem Parser support for Korean

[jeeeyul]

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

Take a look at the English version:

meridiem : function (hours, minutes, isLower) {
    if (hours > 11) {
        return isLower ? 'pm' : 'PM';
    } else {
        return isLower ? 'am' : 'AM';
    }
},

I think you may want to do the same (becuase you used the i flag in the RegExp).

There is no capped letter in Korean. I removed unnecessary "i" flag.
