acts_as_bitfield Plugin now Radio Button Compatible

I've patched the acts_as_bitfield plugin to recognize "true" as true so that now instead of having to write:

<%= f.radio_button(:email_activated, true, :checked => ("checked" if @item.email_activated?)) %> Yes

<%= f.radio_button(:email_activated, false, :checked => ("checked" unless @item.email_activated?)) %> No

you can omit the checked argument just like with ActiveRecord boolean attributes:

<%= f.radio_button(:email_activated, true) %> Yes
