Title: Fix for JEASH-28

Hi, this should fix the issue where child DisplayObjects will not respect the alpha property of anything higher up the display list than one level. I attached a test case to the bug report which illustrates the bug. https://haxenme.atlassian.net/browse/JEASH-28

Basically my approach is to keep a merged alpha property in all DisplayObjectContainers so you don't need to manually walk up the display list every time you need to calculate alpha.
