- Added a listener when the extension is installed to initialize the storage array
- restructured logic so that it flows a bit better
- removed some unneeded functions as they caused bloat

- fixed the board menu small image tiles due to the recent changes to Trello.
- includes multiple changes to simplify manipulation of CSS and HTML elements
- the browser extension is overall, "quieter" and not doing so much when detecting tab updates
- removed JQuery, Bootstrap, and files as these libraries and files are not needed

Hello I fixed a bug where the background image for a trello.com board was no longer functioning. I removed some unnecessary files and also updated the extension icon images. I remove some code that was intended to detect the domain of trello.com but instead switched to the domain detection using "show_matches" in the manifest instead.
