No, definitely not restricted to singlespeed. Most road bikes in the 70's and 80's had horizontal dropouts and rear derailers. Some horizontal dropouts have derailer hanger holes, some don't (mainly on cheaper bikes). On the ones without derailer hangers, there's an adaptor thingy that fits over the axle and hangs down to provide a mounting point for the derailer. Sort of like a replaceable derailer hanger on an aluminum mountain bike...
Vertical dropouts are considered better for a geared bike nowadays, because the axle can't move around, so it'll never slip out of place or track imperfectly (assuming the frame is in alignment).

Yes. The frame pictured has a hanger on it. Look below the dropout.

Though it's technically called a track end. The ones pictured above are horizontal whereas what you have are track ends (though they're far from exclusive to track bikes, especially these days).
Not to be pedantic, it's a useful distinction particularly if you stop off the at the LBS for bits 'n' pieces.

make sure you get the QR nice and tight though, I had a friend ride right off of his rear wheel. It didn't cause an accident or anything, just had to tighten it up.
