FactoryGirl and DataMapper

[bgentry]

Hello,

I'm working with factory_girl and the latest version of DataMapper. As
documented in this blog post ( http://blog.antarestrader.com/posts/143
), the latest versions of each have compatibility issues due to the
fact that DataMapper gives a different meaning to #save! than
ActiveRecord does.

His solution seems to work, though I'm not sure if there's any issues
with older ActiveRecord setups out there. Anyway, I'd like to see
startrader's work ( http://github.com/startrader/factory_girl )
integrated into the main factory_girl branch so that the default gem
will work with DataMapper.

Please post here if you think these changes will causes any problems
with preexisting code or if you have any other thoughts on the issue.
