For now, do not allow UI Automation live region events with the same text within a short time of each other. Multiple apps in windows 10 (Maps, Store etc) have buggy events. No runtimeID check can be made here as in many cases multiple elements in a list (E.g. store updates for each app) are firing all at the same time.
* Added a _shouldAllowUIALiveRegionChangeEvent property to UIA NVDAObject. This is private as it may be changed or removed in the future when live region events are rethought in Windows 10. this property compairs the text and time against the last liveRegion change.
