missing dependency adzerk:boot-reload:jar:0.6.0-SNAPSHOT in clojars

cloning this locally and running `boot package` yields an exception:
```
clojure.lang.ExceptionInfo: Could not find artifact adzerk:boot-reload:jar:0.6.0-SNAPSHOT in clojars (https://repo.clojars.org/)```

It looks like it should be `boot-reload 0.6.0`
