Added some extra information how a good MR looks like

Remove periods from merge request

Start development Key seed id from 1 to prevent `Couldn't find Key with id=0` crash on MySQL.

Move Project's service specs to the correct location

Update guide from 6.0 to 6.7

The "Merged by" and "Closed by" statements end with an extra space followed by a period. This doesn't seem necessary to me and not having the extra space followed by a period looks better to me. Also, the top of the merge request doesn't have the sentence ending with a period.

	CHANGELOG

Replace gemoji with open source PhantomOpenEmoji

Currently this method responds with `text/html`. It is kind of unusable
if you open it in a browser. The browser thinks it is HTML and renders
it as HTML, meaning new lines are dropped. So it's very hard to
distinguish where the key starts and where it ends.

This commit changes the content type header to `text/plain`.
