## Issue
85 Add additional GA events
## Approach
Instead of placing analytic calls all over the GUI code (no separation of concerns), try to do it through a redux middleware instead.
## Changes
- Updated GA event and parameter naming after understanding how reporting works.
- Removed unused analytics.
- Add `/extras` to the precommit hooks (lint, prettier).
- Remove `preinstall` since these modules don't exist anymore.
- Fix missing brace if one single-line if-statement.
