attachment_id conditions works like homepage

[starnetwork]

Hi,
in wordpress attachment_id pages
(for example: ​http://demo.opensourcecms.com/wordpress/?attachment_id=xxx)
the conditions of homepage, both is_front_page and is_home will work on this attachment_id links like on homepage.

I don't know if this is the best approach to the problem but I've solved the problem adding condition for the attachment_id, it must be a numeric value to be passed to absint, otherwise it will return 0 and then later on the condition of marking it as a attachment fails.

Although might be better to change the condition, I don't know...

Could not reproduce the original bug neither in 3.4 nor in 3.5-beta1.

The unconditional absint() is consistent with the other ones above:

If attachment_id is not a numeric value, then it's not a valid attachment page.

Feel free to reopen with more information if there's still a problem.
