Issue edina/fieldtrip-spatial-memories/issues/30: Project now recognising spatial memories config.xml

The config.xml file should now be in the project root, not in www (see http://devgirl.org/2014/02/10/3-cordova-cli-changes/).
Fabfile has been modified to symlink to custom spatial memories version in www.

Added <preference name="DisallowOverscroll" value="true" /> so that screen no longer bounces.
Issue #49 upgrade to cordova 3.5
