Documentation updates remain uncommited

[arekbulski]

There are 2 open PRs with plenty of documentation text, and we should sort it out before shipping 0.8. I am opening this Issue so that it doesnt get forgotten.

• style_guide ideas by KOLANICH kaitai_struct_doc#7
• User guide documentation update kaitai_struct_doc#5

I am asssigning @GreyCat because he seems to be the ultimate authority here and noone else will merge it on his own.

This is one of last 2 tickets before 0.8 is ready to ship. @GreyCat

I don't think it's actually a stopper for v0.8. Anyway, these documentation contributions refer to older sections. And, even if we're missing some docs for v0.8, probably it's still ok release and finish documentation later (as we don't ship it together with the compiler, we just update http://doc.kaitai.io).
