Fix score number formatter spec expecting the wrong result.

- -2049 should be -2k not -2.1k.
- Added a spec to test that -2050 becomse -2.1k instead (as that is what
should be expected).

Add convenience method for formatting score numbers.

- That is, you can just give it your `NSNumber` instance and it will
take care of the reset. Woop woop.
