Added support for tables that have computed columns or indexed views

As noted in the [SQL Server documentation](http://technet.microsoft.com/en-us/library/ms174393.aspx) and in this [StackOverflow question](http://stackoverflow.com/questions/8388272/error-deleting-all-tables-delete-failed-because-the-following-set-options-have) tables that have computed columns or indexed views need the QUOTED_IDENTIFIER option to be toggled on before CRUD operations.

This pull request adds support for running the bulk copy on databases that have such tables.
