New macro detection features (#7359)

* Adds battle config macro_detection_punishment to ban or jail characters. * Adds battle config macro_detection_punishment_time to adjust the duration of ban/jail for players who fail the captcha challenges. * Adds script command macro_detector which invokes the captcha challenge. * General cleanups to the jail functions to remove duplicate code. * General cleanups to the macro punishment calls to remove duplicate code. * Ending SC_JAILED will now properly remove the jail status rather than trying to reset the timer to 1 second resolving any possibility of players getting stuck. Thanks to @Lemongrass3110!
