Complete rewrite, with a full redo of the UI. Now you can select which characters etc you want to search for, plus extended settings to show and hide shops.
NOTE: If you customised the shop list, remember to take a copy before updating. There isn't a customisation UI, but it'll be coming as soon as I write it...
The shop JSON has changed, but should be fairly self-explanatory from the already-existing examples. Use %s for where the search term needs to go, instead of the parameter silliness I had going on before.
