beesh: Die when called with unknown option

[donald]

Currently, when beesh is invoked with an unknown option

./bla.be0 --nonsense

it happily continues. I can't see that this ise usefull enywhere.

Make beesh abort when called with an unknown option.

I think this is intended. You will find @ARGS in $OPTIONS sorted by beesh-known -- beesh-unknown

./bla.be0  --lala huhu lala --check

results in

OPTIONS=--check -- './bee-files/make-4.2.1-2.bee' '--lala' 'huhu' 'lala'

which is ... brilliant !

I wouldn't let it die.

I know, but didn't find a single usage of that.
