Request for more designated Rank powers (regarding news and sales)

[SpeedyD]

Bug as reported:

(release/release-2.0.0 branch, last commit parent: 549e010 ))

URL of page: N/A
Description of bug: Only users with the 'edit_pages' (or Edit Text Pages) power can comment on sales posts that are still in the Preview period... and that's odd.
How was the bug caused (exact steps to reproduce): Make a sale. Delay comments. Find out that some of your staff can't comment on the sale.

Further details

Another non-bug bug report from me..

Long story short. I recently made a sales post on the LK site I'm involved in and delayed comments so that the staff could leave sales comments before users replied. One of the ranks we've set up is for Official Artists, who do art and make adopts, but have no task directly related to the site. They were completely unable to respond to the sales post while it was in Preview.

I later found out it requires the 'edit_pages' power.. Which.. is honestly confusing? Editing pages is not commenting on sales posts.. Heck, editing pages is not posting news or sales, but it's all under the same header.

So my suggestion here was originally born out of a designated rank power which allows users which have it to comment on sales- a rank power I definitely still explicitly need.. But perhaps also rank powers that are specifically for setting up news and sales posts?

Noting since I'm thinking about it that it's probably prudent to have a breakdown like so:

• News edit power
• Sales edit power
• Sales comment power, which sales edit power inherently includes but which may be granted separately since official, guest etc artists who should have this access but do not otherwise handle admin affairs are a fairly regular occurrence.
