Major update of Selectricity to work with Rails 2.2.2 from 1.2!

This included a large number of changes:

- removal of randarray.rb (features are not in the new version or ruby)
- removal of sparklines plugin and replacement with gemified version of
  sparklines and sparklines_generator
- addition of act_as_list plugin which is no longer in rails
- disabling of all API code because action_web_service is deprecated in
  favor of active_resource (!!!!)
- large number of miscellaneous updates to do the new rails 2ish

I've commented out the new features in the views (i.e., embedded) as
this is going to replace the LIVE version of Selectricity. We should
then test this well, slowly enable the new features, and get the tests i
old_api_code back work with an active_resource interface.
