Update API Definitions comment related operations (and tutorials).

[inertia186]

As an application developer, I want to know everything related to comment operation, so that I can broadcast content that correctly reflects my intent.

The API Definitions comment broadcast operation lacks details on broadcasting content (post/comment). This op needs to enumerate the params that are allowed, what values can be passed, and what related operations can be included in the same transaction and why.

See: https://developers.steem.io/apidefinitions/#broadcast_ops_comment

AC

• [x] comment operations have complete details
• [ ] ~related tutorials that affect comment operations link to the comment broadcast op~

Second AC removed in favor of putting that work within steemit/devportal-tutorials-js#82

I have blocked this until https://github.com/steemit/devportal-tutorials-js/commit/e7f92d796bd2f024a1a7a22a0b4706ce7a2e2407 is merged into develop then will create branch corresponding to this issue to add links to devportal @relativityboy @inertia186 @feruzm

@roboza - That would be a very brittle way to ad those links. I've created steemit/devportal-tutorials-js#82 to take care of them. You should be unblocked.
