Improve german support (#222)

Browse Source 
* german: fix case in currency names

Also, add more tests for german language.

* german: default to amount of euros, not cents

If a non-float number is provided, interpret it as a quantity in euros,
not cents.

* german: handle "ein Euro" vs "eins Euro" exception

* german: prefer "einhundert" over "hundert"

"hundert" is usually colloquial (even if widely used).

Exception: "eintausendste" and "hundertste" are special cases, here
"hundertste" and "tausendste" are usually preferred (see Duden).
