Greasy Fork

* Fix a bug where new shops won't show (and none show on first install)
* Add a selection of proxy sites

* Added setting to make links open up a new tab. Defaults to on, can be turned off in the settings.
* When all shops are turned off, a message will now display informing users how to activate sites/shops
* displayNewShops parameter removed (was unused on the frontend)

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.
