Numbers should not be shown as errors

[laritakr]

Currently the digits 0 through 9 do not show as errors, but anything 10 or higher does. Either number highlighting as errors should show according to the rules for writing numbers ( http://www.grammarbook.com/numbers/numbers.asp ), or they shouldn't be highlighted at all.

It'd be nice to see this solved... though the odds of it seem low now

It's fixed in PR #34. A fork with this and other changes is available on Github and NPM.
