Title: fix yaml header problems

### published
When posts are private (for example), yaml should include
```yaml
published: false
```
but currently exitwp just add
````yaml
status: private
````
which has no effect.

### date & wordpress_id
yaml.saft_dump() will add extra single quotation marks to string/unicode variable.
send the raw python type ( datetime for date, int for wordpress_id ) will fix this tiny problem.
