implement select (#45)
* select, second go using new multiline code * implemented internal delete_str, added tests * delete_str_internal must not put non deleted strings into history. Ie ctrlc should not change history * delete_str was taking lines out in the non delete case * corrected comment * fixes after feedback. Plus multichar bugs. change modal sample
