Implemented enhancements 4 and 6 .
'werror' is now an option that may be specified for any rule in a config file. This new setting will work on any rule (even rules already developed.)
'verbose' is now an option. Rules may now call print_verbose(str) to provide additional output when this setting evaluates to true.
Note: for both new settings the true values are y, yes, t, true, on and 1; false values are n, no, f, false, off and 0.
