Handle huge posts in forum

[chris34]

Posts with a size of >2 MB raise multiple issues: Akismet has some problems evaluating them. Other users with a low bandwidth (mind mobile users) experience slow loading or even a timeout.

IMO we have multiple options:

• restrict the maximum size of a post
• automatically open a paste, if more than size x is pasted into a post field (should be possible with some JS)

Honestly, limit posts at 500kiB if even that large and ask people to put logs etc. into paste bins.
