[Discussion] Move Akismet site and apiKey properties to siteConfig?

[pingu8007]

I'm looking to make staticman working with multiple site but the Akismet configuration is confusing me. Although they were mentioned before (#83, #339), whether it should be parts of staticman.yml is not clear. There are 2 opinions exist:

1. site should be the url where staticman instance hosted.
2. site should be the url of gh-pages where guest posting comments on.

I suggest moving those 2 properties to siteConfig for following reason:

• By forwarding but not owning apiKey, a single instance can process as many site as possible.
• According those material, site is parts of Akismet's price calculation.
  • What’s an API key?
  • Should I choose a free or paid subscription?
  • Adding Sites to an Existing Plus Subscription
  • Error codes 10007 and 10008
  • API docs:

    ### PARAMETERS
    `blog` (required)
    The front page or home URL of the instance making the request. For a blog or wiki this would be the front page. Note: Must be a full URI, including http://.
