Adding documentation to +polymorphic_url+

documented.

Performance regression in AR::Base.respond_to?
Creating options for schema dumper.

These options make it easier to change the config from
ActiveRecord::Base to use something else inside of the SchemaDumper.
Making proper_table_name take in options.

The options will specify the prefix and the suffix. Also, I'm moving the
method to be an instance method on the +Migration+ instance. This makes more
sense than being a class method on the +Migrator+ class because the only
place that uses it is on a +Migration+ instance (in a method_missing
hook). The logic for the Migrator shouldn't be doing any work to
calculate the table name, it should be the Migration itself.

Also made some small indentation fixes.
