Fix offset map on logged-out home page

Not sure why it got offset? But oh well...
Bump app version, don't update Google Maps to APIv3

The email they sent is as follows, but it seems like the wrapper is working fine:

Dear Google Maps API Developer,

We are contacting you because your email is associated with the Google Maps JavaScript API v2 key being used for the following domains:

wheredoyougo.net
As you may be aware, JavaScript Maps API v2 was scheduled for shutdown on May 19, 2013. After listening to feedback from developers we decided to [extend the deprecation timeline](http://www.google.com/appserve/mkt/p/jwmzFe7Mw28wqyXWGCwC6m1DXp5p2WkE2PFrKEOI3B-Iiki0xNlFwN-zUI7EL_3dKQuWbRdsiSDecx_G0ZDbLpl_FYQGYR4YMW9tdutQqJ4l_OnEEvmV7c218XOcHRHj74otFutmXSvoZMlupXriNCnDHXI=) by six months, to November 19, 2013 to allow more time for migration to v3 of the API.

On November 19, 2013 we will deploy a JavaScript wrapper that attempts to automagically turn remaining v2 maps into v3 maps. Though we expect this wrapper to work for most simple maps, we cannot guarantee that your maps will continue to function. We therefore highly recommend that you migrate to v3 before November 19. The good news is that Google Maps JavaScript API v3 is more robust and feature rich than v2, and we’ve written a [guide to assist the migration](http://www.google.com/appserve/mkt/p/SmTHpEsWPQORAS7TdduaCBH3q6kZ5Uc3jAruGAcP0yoA3iWetDsW_GSYYdeQ3tINKQWSx4X_OlypWh-3p0-jbc_bscyqLLM1qBXFsXy2Rnc8jFcsKVGw6dbuLBLu5xVSMEwACvEFfFBNS1xsYHY5xlOf8eUIjsOFhxOShjrIYJNBBAamo3NgOF55sMZW6j2sM8w6UxMPD5Qy_X7OQg==).
