[horde] Kronolith javascript error

[김 덕곤]

When : editing event.

Javascript call stack :
KronolithCore.updateFBDate(start=null)
KronolithCore.editEventCallback(r=Object { event={...}})
HordeCore.doActionComplete(action="getEvent", resp=klass { 
request=klass, transport=XMLHttpRequest, readyState=4, more...}, 
opts=Object { callback=function()})
HordeCore.doAction/ajaxopts.onSuccess<(t=klass { request=klass, 
transport=XMLHttpRequest, readyState=4, more...})
Ajax.Request<.respondToReadyState(readyState=4)
Ajax.Request<.onStateChange()

Problem : start=null?

following code returns null.

Date.parse(ev.sd, Kronolith.conf.date_format)
Date.parse('2014년 08월 22일', 'yyyy년 MM월 dd일')
