Changes necessary now that zero values accepted in AmountFromValue

- Add an accept test for zero amounts, and a reject test for negative
  amounts
- Remove ugly hack in `settxfee` that is no longer necessary
- Do explicit zero checks in wallet RPC functions
- Don't add a check for zero amounts in `createrawtransaction` - this
  could be seen as a feature
