Performance enhancement for Str Class (see pull request #1180)

Fixed a problem with `Eloquent::get_dirty`

Auth token now nulled on logout

[#1261] get_key now pulls from $original instead

This is in reference to issue #1261, where Model->get_key() returns
the key from the $attributes instead of from the $original property.
This breaks the functionality of a model with a primary key that may
change, as the SQL generated will be something like:

UPDATE `model` SET `key` = 'new-key' WHERE `key` = 'new-key';

Which won't update the model in the database.
