Loadout fixes and loadout points config option

- Adds a configuration option for loadout points.
- Fixes the blue plaid skirt lacking its own unique type, causing
runtimes due to the mismatch between its display_name and
initial(display_name).
- Fixes the gear selection table using a fixed width.
- Fixes the restrictions column not consistently being added.
- Fixes the header and footer lacking the proper column span to account
for the restrictions column.
