Explain how to load data for testing

This is a fairly common query, and not too complicated where the data only needs to be loaded.

Loading data then editing it is more complex, and not covered here.

+After installing but before creating any users or data, import an extract with [Osmosis](http://wiki.openstreetmap.org/wiki/Osmosis) and the [``--write-apidb``](http://wiki.openstreetmap.org/wiki/Osmosis/Detailed_Usage#--write-apidb_.28--wd.29) task.

+Loading an apidb database with Osmosis is about **twenty** times slower than loading the equivalent data with osm2pgsql into a rendering database. [``--log-progress``](http://wiki.openstreetmap.org/wiki/Osmosis/Detailed_Usage#--log-progress_.28--lp.29) may be desirable for status updates.
