Browse Source 
- The inventory page now shows status of seen products as of when they were registered,
   not as of now.
 - Renamed a placeholder in fragments.html to be more intuitive.
 - Added a type field to the event table in the database, so that complete events can
   be constructed without complex logic.
 - Refactored to support the above changes
