Fixed a bug in  when using has_many association with :inverse_of option and UUID primary key.
DirtyModel uses a hash to keep track of any changes made to attributes
of an instance. When using the attribute_will_change! method, you must
supply a string and not a symbol or the *_changed? method will break
(because it is looking for the attribute name as a string in the keys
of the underlying hash). To remedy this, I simply made the underlying
hash a HashWithIndifferentAccess so it won't matter if you supply
the attribute name as a symbol or string to attribute_will_change!.
make sure both headers are set before checking for ip spoofing

like +:anchor+, +:script_name+, etc. but this is currently not
documented.
