Add region_wide option to ffxiv shopping list

[Alex Cohen]

Theres a new region_wide option, this should be set to false by default. Add it into the FE so that people can check it if they want to.

{
    "crafting_list": {
        ...
    },
    "home_server": "Famfrit",
    "region_wide": false
}

Just need to add something like this to the shopping list page
