Well I WAS doing another project but got sucked into this one, which needed doing for a while now anyway due to various infobox template changes.
Changes for Staff Exclusive item pages:
-Infobox (lots and lots of switches in this one)
-Page format (reducing, removing "vendors/trivia" and bullets etc)
-Adding new "{{staff exclusive item image}}" tag to all associated images, including icons. A few things need to be reuploaded to better names, I'll get to that later.
Changes for Obsolete item pages:
general reduction/same sort of stuff.
And made sure that none of these items show up in a category search for people who use categories to plan outfits and loadouts.
Thanks to HexZyle and DragonFaku for most of the information on the Staff item pages, I imagine it was somewhat difficult to get most of the time.
Please check over my edits to make sure I've not made mistakes. Icytea already found one page with derps regarding accessory slots. As I said on his talk page - Would it be safe to assume that the costume armor items have armor rear slots, if they have all the other slots? Recall that this slot was introduced to the game much later than other slots. Is there a way to view this data in the files? It's such super, duper, supremely, extremely, (un)important information ;P
Some thoughts on the position of star info (should we also add arsenal item type information in this section)? Might be applying that to other infoboxes soon.
Otherwise, should be done updating outdated templates with new templates.
