Upgrade to Rails 3.1

This may take some work. We depend on spatial_adapter, which doesn't appear to support Rails 3.1.

Looks like activerecord-postgis-adapter should be a reasonable substitute, though it may make future MySQL compatibility harder.

Also, ym4r_gm plugin was out of date. I tried the new gem , but it has an initialization issue (see https://rails.lighthouseapp.com/projects/8994/tickets/4016-railsroo...). Hopefully I can fix this.

Even when installed as a plugin, ym4r_gm doesn't seem to want to work with Rails 3.1. Perhaps it's time to remove it.
