added Bandango.jsonCamelizedReviverHelper

it applies `camelize` to every *key* when processing the JSON
ItemsController's model is current `category`. ItemsIndexController needs that category to display data
refactored ItemOnFormMixin.

Changes:
- `itemSelected` should be called with `super`. It will return the item
selected
- Not using `keyPath`, `valueKey` or `onSearchComplete`
- Now pushing items on `transformResult` callback method
no need to access the store to find the item anymore
