fixes case where unmarking a complete todo which belongs to a recurring pattern results in two todos that both keep on recurring. With this fix a new todo will only be created when there are no active todos left belonging to that recurring pattern
fixes tests that failed because of previous commits
adds some named_scopes, inspired by http://railscasts.com/episodes/108
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.
