Allow Report on blog posts

[Ubersmake]

Is your feature request related to a problem? Please describe.
"Report" is only available on game pages and comments. I've run into at least one blog post that links to a download for a game not associated with the poster, much less an Itch account publishing games. This is at best piracy and at worst malware, and neither is a great look for Itch.

Describe the solution you'd like
Add reporting functionality to blog posts.

Describe alternatives you've considered
I've considered and sent a support email.
