Add script to fetch browser history from local cache

[andweeb]

Local browser history cache locations:

• Safari: ~/Library/Safari/History.db
• Chrome: ~/Library/Application Support/Google/Chrome/Default/History

Querying the local cache probably requires some Python 2 script that returns history data in JSON for a given browser. Looks like this can be achieved using the hs.sqlite3 module already exposed in the Hammerspoon API.

This is needed to add browser history actions with select mode for browser application entities.
