Hobo Hobo

I've just been playing around with the :type argument that hobo fields adds to virtual field declarations. This is the example given in the hobofields tutorial:

>>class Advert
    attr_accessor :my_attr, :type => :text
   end
>> a = Advert.new
>> a.my_attr = "hello"
>> a.my_attr.class
=> HoboFields::Text

This is great, however, it seems to be broken for plain types (ie. any type that isn't one defined in hobo fields). When (in my hobo app) I define an attribute as:

attr_accessor :my_attr, :type => :integer

I get the following error: "uninitialized constant Integer::COLUMN_TYPE" on /Library/Ruby/Gems/1.8/gems/hobofields-0.8.10/lib/hobo_fields.rb:66:in `can_wrap?'. It seems that the column types aren't being defined (or populated) for non-hobofields types.

In the class definitions for hobofields types there is always a COLUMN_TYPE constant defined, but for old types I think it either needs to be set in the classes themselves or hobofields needs to look for the COLUMN_TYPE in it's own code somewhere.
