Made bool parameters switchable so the make more sense

Browse source 
The previous behavior was wrong in a way, that default values
like "use lower case" defaulted to true and using the -L param
would not set it to false, but simple keep the true default which
made the parameter useless.

Now all parameters still use the same defaults but setting the
corresponding flag on the CLI will negate the default, so using
-L on the CLI would set "useLowerCase" to false instead of the
default of true.
