EXP-929 FIX -- First Direct Delivery item purchased while logged in: Received Items folder visible in inventory and item not visible in Received items panel - no badge count update
* Inbox and Outbox inventory panels now live in their own XML files and are hot loaded into place when appropriate, like when the "Received Items" folder is first created, for example.
* The Inbox and Outbox panels now show relevant default messages when the folders are empty or do not exist
* Added LLInventoryCategoryAddedObserver, a new inventory observer type to observe added folders
* Hacked LLInventoryPanel to properly set up inbox and outbox inventory views for the "Received Items" folder and the "Merchant Outbox" folder that aren't created with the proper system folder type
* Changed inventory badge count computation to use LLFolderView rather than the inventory directly
* Applied various focus, selection and other inbox fixes to the outbox
