This patch allows urls to be of the form :module/:controller/:action as well as :controller/:action/:id where :id is no entirely numeric by determining if what would be :module corresponds to a directory in app/controllers. If it does not then the :controller/:action/:id scheme is used.

Added a better exception for when a type column is used in a table without the intention of triggering single-table inheritance. Added that single-table inheritance will only kick in if the inheritance_column (by default "type") is present. Otherwise, inheritance wont have any magic side effects
