Add keywords to Slices

Attach the keywords used for Settings search to Slices.
Their primary use is helping match synonyms for presenters
which display slices without explicit Uri requests, like a launcher.

This changes:
- Updates database scheme
- Adds to SliceData object
- Grab keywords in the SliceDataConverter
- Set keywords on all slices
