fixed to be compatible for Wordpress 3.5.2

The current code doesn't import into Wordpress 3.5.2, I investigated and made the changes necessary to have them work together. My PHP isn't exactly up to scratch, but the changes that are supposed to be made are:

1) <wp:post_type> should be "post" and not "entry"
2) <wp:status> should be "publish" and not "published"
3) the </channel> tag closes prematurely (and twice!)
