Merge pull request #178 from shingara/rails-3-2

Upgrade to Rails 3.2
Reverted to using `gem 'rails', '~> 3.2.0'`, since all rails dependencies are installed anyway (See https://github.com/errbit/errbit/pull/178#r805414)
Prevent rake 0.9.2.2 from failing when clearing default task

rake 0.9.2 would (apparently) wouldn't fail if you tried to clear
a task that wasn't defined.  

This closes issue #179 where trying to run the db:seed rake task 
would fail with the error Don't know how to build task 'default'

Tested on ruby-1.9.2-p290 and ruby-1.9.3-p125 only, rake 0.9.2.2
