Fix for twitter API v1 closing down, fix for Google Maps not showing custom map types.

TimelineJS will now use Oembed instead of the get tweet restful api from v1. This change means that avatar images will no longer be shown since they are not available in the Oembed json. closes #434

Google Maps api is now using v3.9 instead of the release version
There was a change in the latest Google Map API that causes custom map types to stop working
 More info: http://stackoverflow.com/questions/13486271/google-map-markermanager-cannot-call-method-substr-of-undefined
solution for now is to use API ver 3.9 closes #435

IE7 hook for alternative display was removed. closes #161
Added Afrikaans language
