Add support for table navigation (control+alt+arrows) to MS word with UIA support, by abstracting existing browseMode table navigation code even further. Specifically: Add a new documentBase module which contains: * TextContainerObject, which is an object that can make a textInfo. It contains a TextInfo class property, as well as makeTextInfo, and selection getter and setter. This is now inherited by NVDAObject and documentTreeInterceptor. * DocumentWithTableNavigation: a TextContainerObject that contains table navigation scripts, implemented by abstraction table code that used to exist in browseMode. Now BrowseModeDocument inherits from this. UIABrowseModeDocument's _getTableCellAt was moved into its own UIADocumentWithTableNavigation class, which UIABrowseModeDocument now inherits from, and so dos the UIA WordDocument NVDAObject class, thus now giving UIA word document support table navigation outside browse mode.
