Fixes a bug with the 'Detected Emulator' message

3 months ago I apparently introduced a bug into the detected emulator
message with the code

```
for emulator in emulators:
  print 'Detected Emulator => %s' % name
```

The obvious problem being that the name variable doesnt change per
iteration, it just happens to be the name of the last emulator I
detected.

I am amazed this bug has lasted this long. Oops.

Fixes #178.
