Issue:
'default' validator doesn't work for booleans
Specifically when the default is `true`, but the record's value is `false`:
```
obey.model({
  enabled: { type: 'boolean', default: true }
})

// then elsewhere
validate({ enabled: false }) ==> { enabled: true }
```
Need to add a type check before returning the final value (for numbers as well, in case of `0`).

Pull request:
Fix/bool default
Closes #68
