First stage of attribute refactoring

The following are now arguments to cmd2.Cmd.__init__() instead of class attributes:
* allow_redirection
* multiline_commands
* terminators
* shortcuts

Added a couple read-only properties for convenience of cmd2.Cmd accessing immutable members from self.statement_parser
