Log sendpass sender & time, show in info. Option to kline user@host instead of *@host

as far as the kline commit is concerned, I have 2 questions

#1 if (!config_options.kline_ident) should probably move to a function that klines according to the option instead of being copypastaed errywhere, but idk what i should name that function
#2 the option name should probably not be kline_ident...
