Packages create, index, show example

I'm sending this pull request mostly to show you guys how the Packages are coming along. I figured out how to properly map case classes to query results, and that'll make our lives easier so check that out in the Packages model file. So far:
- Packages model (except need to make changes for status once those are merged in)
- Index/Show/Create Packages
- Query logic is all in the model (except for create, I have yet to move that)
- Case class Package maps to query results and vice versa, so it's easier to create views for Packages.

I'm not sure how to generalize the queries to put them into a trait that can be commonly used by all queriable items. If we can get that to work, that'd be quite awesome.
