make quick.done depend on quick.bin again
assume build.release when maven.version.suffix is set
if starr.use.released fetch Scala ${starr.version} for STARR

I recommend creating a build.properties file as follows:

```
locker.skip=1
starr.use.released=1
```

This will download the Scala version specified in starr.number,
use it to build quick, skipping locker.
