Temporarily hide Hive OS X and link to Hive Android on Google Play

Links to Android and OS X wallets now point to Hive's web wallet.

So current traffic from bitcoin.org is basically redirected to a web wallet that hasn't been submitted in a pull request, users expect the OS X or Android app and get the web app instead.

In the absence of critical feedback, this pull request will be merged on June 28th.

@jsuder If you want to keep your OS X app listed, can you provide a dedicated page for Hive OS X?
