won't blow up if no association found

[seamusabshere]

currently on associations (attr.associate) and inline associations (attr.store [...] :foreign_key => X), you can say

:create => true (will use find_or_create_by_X)
:create => false (will use find_by_X)

you can't say

:create => :raise

which would stop the import if there was a missing association, which might indicate a problem with your data.
