1. The API supports batching -- updated the code to use that. Retained string as the parameter (instead of changing it to array) so that existing clients won't be affected.
2. Make `doFetchSubCount` a batched command by default through an idle timer. This way, none of the clients need to collect IDs -- it's all done behind the scenes.
3. Added minimum of 5 minutes between each sub-count fetch for a claim ID.
## Issue
- Each tile was checking against 4 blocklists (blacklisted, filtered, muted, commentron) on every render. Loading the front-page with Cheese alone caused 1400 calls.
- This is also part of the reason why pressing Back into the tile list takes forever.
## Fix
Since we still need to perform the checks at the app side for now, tried to memoize the operation through a selector.
## 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.
