MirrorDisplays latest

Error installing:

```
Error: uh oh, could not identify primary container for /Library/Caches/Homebrew/mirror-displays-latest.zip
```

Think the problem is URL 
`http://www.fabiancanas.com/downloads/MirrorDisplays.zip` 
fails if it's not referred from Homepage 
`http://www.fabiancanas.com/Projects/MirrorDisplays`
...
Might have to fake the referrer somehow.
