Bump cascalog/midje-cascalog deps, source .bashrc in setup.sh

Fixes the hack in #318 by bumping midje-cascalog dep (thanks @sritchie for beasting on that repo). Added bonus: Bump cascalog dep to 1.10.0 and lein-midje to 3.0-beta1. 

All tests pass. @robinkraft, dude, you saved me a world of pain with your setup.sh script, awesome:

```bash
$ lein midje
All predictions (607) came true.
```
