jnfeinstein 8b451f0084 Add support for polymorphic relationships using the POLYMORPHIC setting. 
This commit adds support for two settings:

FOREIGNTYPE - A field that is used to store the type of the owner.

POLYMORPHIC - A shortcut to set FOREIGNKEY and FOREIGNTYPE to the same
value suffixed by "Id" and "Type" respectively.

The type is stored as the table name, which I thought might be useful
for other queries.

The biggest gotcha of this commit is that I flipped the definition of
has_one and belongs_to. gorm is very flexible such that it didn't
really care if it was a has_one or belongs_to, and can pretty much
determine it at runtime. For the sake of the error, I had to define
one of them as belongs_to, and I chose the one with the fields as
the belongs_to, like ActiveRecord. The error could probably be
genericized to "gorm cannot determine type", but I think it's nicer
to tell people DONT DO PATTERN XYZ CAUSE IT WONT WORK. Functionally,
it doesn't matter.

jnfeinstein 794e1ba20b .Count() should always use ToSnake'd foreign keys. 
It looks like gorm always uses the snake form of a column by
convention, as seen by searching DBName in scope.go. These counts
were erroring out without the ToSnake'd foreign keys.

Further, the code for has_many and has_one becomes the same (which
makes sense), so I combined the two cases.

FieldValueByName in utils.go does now only what it should and has proper errors.
