adds a new feature to the telnet action plugin
This change adds a new argument to the telnet action plugin that will cause the module to send a newline character before trying to login. This is convienent when using telnet over a console connection that needs an initial newline character to start the login process. This change also will cause the sent command and command response to be displayed on stdout when running in verbose mode (5 v's).
