Update instructions for downloading extra assets

and the instructions for running without additional assets

"make update_assets" and util/snis_update_assets.sh are no longer
the way things are done.  Instead bin/snis_update_assets is used
via snis_launcher.

 <h2><a name="additionalassets">Step 5: Download additional assets</a></h2>
 <p>If you skipped step 4 and didn't build the openscad models, they will be downloaded
 in this step, along with some other things. This step requires an internet connection.
 If you performed step 4, you may skip this step though it is not recommended,
 as you will be missing some additional solarsystem assets. As a non-root user:
 <pre>
 <blockquote>
-  make update-assets
+  ./snis_launcher
 </blockquote>
 </pre>
+Then choose option 8, "Check for asset updates and set up assets".  This will copy assets
+to (by default) into $HOME/.local/share/space-nerds-in-space/ and download additional assets
+over the internet.
