NOTE: All "sunspot:__" rake tasks renamed to "search:__"

[Subhas Dandapani]

We have included the sunspot-rails gem which comes with its own rake tasks which begin with "rake sunspot:__" Instead of overriding their rake tasks, we simply changed our namespace.

So instead of the old "rake sunspot:start", you'll have to run "rake search:start", and similarly everything else.

The wiki pages have also been updated with the same info.
