DEV: AST transformers supplied to `InteractiveShell` can reject input....
DEV: AST transformers supplied to `InteractiveShell` can reject input. * Adds a new exception class, `InputRejected` to IPython.lib.security. * Updates `InteractiveShell.run_cell` and `InteractiveShell.transform_ast` to allow user-supplied AST transformers to reject input by raising an `InputRejected`. * Adds tests for the above behavior.
