Moar

Moar docblock tweaks and updates .. nothing big, but when I ran apigen against the files it spit out a few more things to fix.  I'm also going to start tagging functional groups with @package ... this will help when it comes to navigating the docs.

You can see the apigen docs http://elkarte.github.io/Doc/index.html  and the start of the packages on mentions and attachments so you can see what I mean.
