Norwegian Uplift by gealodge

This may fix #110 but was not the motivation for the fix

Changes proposed in this pull request:

• 'lang_NO.py':

  • Removed hyphen between tens and units (e.g. 92 should convert to nittito not nitti-to)
  • Fixed currency conversion (this was v broken)
  • Corrected ordinal_num (looks like this had not been changed from copying English)
  • removed comma from long word form numbers

• 'test_no.py':

  • Created Norwegian test cases file with test cases

Status

• READY
• HOLD
• WIP (Work-In-Progress)

How to verify this change

I have added hopefully quite comprehensive tests for the changes I have made and generally basic tests for Norwegian. Specific examples include:

>>> num2words('92', lang='no')
'nittito'
>>> num2words('1345', lang='no')
'en tusen tre hundre og førtifem'
>>> num2words('5', lang='no', to='ordinal')
'femte'
>>> num2words('5', lang='no', to='ordinal_num')
'5.'
>>> num2words('12', lang='no', to='currency')
'tolv kroner'

Additional notes

There were no tests, these needed adding. The currency conversion was completely broken, essentially dividing the numbers by 100 before converting. Hyphens and commas don't belong in Norwegian numbers like that, so I've removed them. I had to do a big shift around for the ordinals to get that working.
