Use custom fcrepo.war file from our branch of hydra-jetty

You'll need to pull in the latest hydra-jetty:
```
rm -rf jetty
rake jetty:download
rake jetty:unzip
rake jetty:start
```
Regenerate engine_cart
```
rake engine_cart:clean
rake engine_cart:generate
```

Manually create the root annotation container
```
rake triannon:console
Pry > Triannon::RootAnnotationCreator.create
```

Fixes #49
