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.

When you had a synched Eloquent model (e.g. without changed values) but
one of those values is `null`, then that value would be considered as
dirty. `Eloquent::changed` returns false, but the value is present in
`Eloquent::get_dirty`.

This fix makes sure that a `null` value in `$attributes` is only
present in `get_dirty` when it wasn't at all *set* in `$original`.

Changed timestamp function in database/eloquent/model.php from protected to public. Allows eloquent model timestamps to be updated without actually changing any data.

Calling update() on an eloquent model has no way of overriding
the timestamp that should be set if $timestamps is set on the
model. This changes that so it uses the timestamp() function
which is an easy way to over ride the type of timestamps used.

Fix a bug with Eloquent model classes and isset() when eager loading a relationship returns an empty result set.

Allow Model instance an id for first argument in Has_Many_And_Belongs_To::attach() and same for ::detach(). Also a typo fix for the docblock on attach().
