Support for EGO (similar to org-page)

[localredhead]

Hello! I just found blog-admin and I love this tool!

I've been using https://github.com/emacs-china/EGO which is based on org-page. I thought after looking at the code that there are only a few things that need addressed to support EGO.

What are your thoughts? I'd be happy to do this and submit a PR but I'd need some guidance with new post functionality, and the config ignore list is slightly different in EGO.
