c0af173da20cc4560523205bc268677a808a43df doc: default minconf for getbalance should be 0 (U-Zyn Chua)
Pull request description:
- Default `minconf` for `getbalance` is `0` but example in doc was showing as `1`.
- `at least 6 blocks confirmed` now updated to be `at least 6 confirmations` to be more consistent with the terminology used elsewhere in the codebase and documentations.
