FOKUSS

Adding settings page, the logic is not working yet, just the ui and save the setting data to local storage

Made the extension work both in Chrome and Firefox
Improved the pomodoro logic
Added realtime background timer
Improved the logic of popup close or new tab impact on pomodoro timer

Added persestance timer storage to the extension, i will store the current timer and last updated to the browser local storage using the code below and when ever i restart the new tab or close the popup of extension, it still remains in that state

Basic version 1 of FOKUSS pomodoro chrome and firefox extension, just start timer, stop and reset timer
