slight changes to routes in main.py
adding all SlickGrid css and js
basic template/grid_data.html with a view of the entries in a SlickGrid
needs more work

TODO:
  - make GridView.js take an array of '_id', objectids, and wrap the logic for getting entries via REST
  to return an entry to the SlickGrid
  - make the /data route only request _id attributes for the query if type is None
  - pagination?
