message: CHANGELOG update to include CSV item source
diff: * The Progress page sports a new layout to help make sense of all the Pursuits we have to juggle. This is the first iteration of the new page - many improvements are still on their way!
  * Fixed a bug where weapon mods were causing Banshee-44 wish list items to fail to highlight.
  * Fixed a bug with expert mode wish lists and dealing with single digit item categories.
  +* CSV exports now include item sources. These match the DIM filter you can use to find the item.
