Title level of glossary entries

[jecisc]

Currently, glossary entries start with a level 2 title.

I have the impression it could be more readable with lvl4 or 5 titles.

Does someone have an opinion? @juliendelplanque @olekscode

Yeah, we can change it.

But normally heading level should not be used for display style but more for the level of importance from a semantic point of view no?

[jecisc]

I don't know.

Maybe we should not use title then? Depends if we want to be able to easily generate a TOC.

I reopen because of the arguments in #250
