Upgraded to Rails 2.1. This can have wide ranging consequences, so please help track down any issues introduced by the upgrade. Requires environment.rb modifications.

Changes you will need to make:

 * In your environment.rb, you will need to update references to a few files per environment.rb.tmpl
 * In your environment.rb, you will need to specify the local time zone of the computer that is running your Tracks install.

Other notes on my changes:

 * Modified our code to take advantage of Rails 2.1's slick time zone support.
 * Upgraded will_paginate for compatibility
 * Hacked the Selenium on Rails plugin, which has not been updated in some time and does not support Rails 2.1
 * Verified that all tests pass on my machine, including Selenium tests -- I'd like confirmation from others, too.
