[Rails-core] Patch 3705, ActiveRecord::Base#query_attribute

[Zach Dennis]

Mark VanHolstyn found a bug in AR when dealing with MySQL bit fields. It always returned true when 
using helper's like:

     account.is_valid? => true

even if it was false.

I uploaded a simple patch was uploaded to ticket 3705:
    http://dev.rubyonrails.org/ticket/3705

Could this be merged into trunk for next release?
