Move shit around, fix a few bugs

- Added comment/debug message too app.py
- Moved deployment code into a new directory
- Moved requirements file to top-level
- Cleanup some misc comments
- Fixed a bug where duplicates of items would NOT show in the inventory
list (e.g. multiple sticker capsule/key/case/etc would only show once)
found by snuggie.
- Slightly adjusted the feel on the inventory page to give a bit more
space to the inventory table
- Refactored get_parsed_inventory to account for some minor edge cases,
and just general structure issues
- Removed vacdex, its not going to be a thing (at least for a long time)
