Limit Word Count for discussions (and answers)

[NinaHerrmann]

Currently post are of type text and can therefore be 1 GB long (which I guess is an issue in itself, so a default value makes sense.... Anyway ... )
(Split from #91)

Limiting the number of characters is the easiest implementation which I hope also does the job (@pejhab).

Implementation

• additional setting Maximum Characters (default setting?)
• additional setting Minimum Characters
  (- optional field discussions and answers?)
• additional db-field in moodleoverflow_discussion maxchars
• pass value optionally to editor (I think it is maxbytes...)
• unit Test - create post with maxbytes/minbytes

As pjhab said, minimum characters prevent "LOL" Post - Not a lot of meaning and impeding to read a discussion, and maxbytes prevent "rants"

Great to see you are working on this!

May I add that ideally we should be able to set a minimum as well as maximum number of words?

A minimum to fire-proof the discussions against what I call LOL posts and a maximum to guard against "rants". ;-)

[NinaHerrmann]

Thanks for reading over it - sounds like a very good idea! (Although I like "rants" ;) )
I will edit the description!

Just one other thought - To circumvent that limit user might just create multiple post, so it make make sense to have some additional maximum post per discussion limit which kind of related to #134.

I agree. It does make sense.

(But even if it didn't, I would still say we should add the option if it's within our powers. ;-))
