Updated a museum

Adding tags to add info about the El Hierro Free Wifi Hotspots. Here's the general info about them: http://elhierro.travel/el-hierro-la-isla-free-wifi/. The ones I've added are the ones I've used, so they are in the exact location.

Adding a recently visited restaurant in Mocanal on El Hierro.

Adding an Apple Computer + Service Store that I visited recently, but was missing on OSM.
