commit d5ab0ccd4c6223e3dc73728ff09ed60784bc7dca Author: Ryuan Choi <[email protected]> Date: Mon Oct 14 00:57:42 2013 +0900 popup: Change the behavior of adding or removing buttons. Summary: Although user should give the position of button such as button1, current elm_popup changes button's position or style as the number of buttons while adding or removing buttons. So, when application developers add buttons as wrong order or removed buttons, applications may be crashed. This patch refactored the behavior not to change the position intended by application developer. Test Plan: added new test case to test_popup.
