[TIMOB-18522] Windows: Support tile badges, text and image notifications

Windows supports much more than iOS's app badges. We can do app badges in Windows, similar to Titanium.UI.iPhone.appBadge, but Windows supports "glyphs" in addition to numbers: https://msdn.microsoft.com/en-us/library/windows/apps/hh868225.aspx We can also do something that iOS cannot: change the tile image and/or set a message/text. This is equivalent to changing the appicon for iOS. See https://msdn.microsoft.com/en-us/library/windows/apps/hh868253.aspx
