Fix hashery references

This was causing me issues

```
$ rake routes
rake aborted!
cannot load such file -- hashery/opencascade

(See full trace by running task with --trace)
```

After debugging this some, I realized that the hashery library updated 2 months ago and some changes were made to the OpenCascade library.

I have not run any tests on this, but it doesn't cause me issues anymore in development or production right now
