Title: Add a /__heartbeat__ page.

Accessing this page does a simple ping of hbase, returning "200 OK"
is all is well and "500 Server Error" if hbase is down.

This seems to need the latest node-hbase trunk to work reliably; older versions of node-hbase just die if they can't connect to the hbase rest interface.
