Updated abbreviations for be-nl and added spacing.

As pointed out by sanderd17, the abbreviations for be-nl were wrong. In Dutch the respective order is:

* million = miljoen
* billion = miljard
* trillion = biljoen

I also added spacing after the € sign and before the aforementioned abbreviations.
Fixed ordinal

Thanks to sanderd17 again.
Fixed ordinal for 0de, 8ste, 102de, 108ste, etc..
Never realised Dutch was so inconsistent.
Fixed typo.
Fix typo.
Set zeroFormat to null before test.

I wanted to test the ordinal of 0 -> 0de in be-nl, but the test sometimes failed.
