[Title] Fixed when IME disappear, copy & paste context menu is displayed twice.
[Issue#] P130830-03879
[Problem] When IME disappear, copy & paste context menu is displayed twice.
[Cause] When IME disappear, webview is resized.
If parent of copy & paste context menu is resized, "dismissed" callback fucntion to hide copy & paste context menu is called.
And then, copy & paste context menu is updated by setVisibleContentRect() function.
So, copy & paste context menu is displayed twice.
[Solution] 1. Prevent to hide copy & paste context menu automatically using elm_ctxpopup_auto_hide_disabled_set() function.
2. If geometry, visibleContentRect or etc.. of webview are not chagned,
copy & paste context menu is not update again.
