Emails, follow-ups, recording notes, paying bills, etc.

I made a couple of code fixes. One was on the basic sub inventory search, I made it so that closed packages (sub inventory items) didn't show up. Only active packages that are open and/or disabled show up. The closed ones won't show up on this search any more. I also added in some new code to help with the snow owl header menus and bringing in the corp-wide settings for top snow owl navigation. These were things (settings) like corp, customer, location, parts, items, customer queue, etc. They are all tied to dynamic settings per corporation just like the rest of the system.
