Added Errors#add_on_blank which works like Errors#add_on_empty, but uses Object#blank? instead. CHANGED: validates_presence_of now uses Errors#add_on_blank, which will make "  " fail the validation where it didnt before #1309. Added that "   " is now also blank? (using strip if available)

Fixed the Inflector to underscore strings containing numbers, so Area51Controller becomes area51_controller #1176 [Nicholas Seckar]

Fixed that in some circumstances controllers outside of modules may have hidden ones inside modules. For example, admin/content might have been hidden by /content. #1075 [Nicholas Seckar]

Fixed problem with classes being required twice. Object#const_missing now uses require_dependency to load files. It used to use require_or_load which would cause models to be loaded twice, which was not good for validations and other class methods #971 [Nicholas Seckar]

Fixed an exception when using Ajax based requests from Safari because Safari appends a \000 to the post body. Symbols can't have \000 in them so indifferent access would throw an exception in the constructor. Indifferent hashes now use strings internally instead. #746 [Tobias Luetke]
