feat(settings): add global settings menu

[lbragile]

The general settings dropdown needs to have a settings option that provides the following tabs:

1. General

   • Ignore URL parameters and query strings during search
   • Confirm destructive actions (those that delete items)
   • Display Badge Information (extension icon count)
   • Default Group Color
   • Default Group Title
   • Default Window Title
   • Default Favicon URL

2. Theme

   • Dark vs light mode toggle
   • Preview that shows before the Save button is pressed for quick feedback to user - this is simply a "Group" preview that is actually the above toggle
   • Italicize non http(s) protocol tab titles option

3. Backup (background script)

   • Automatic Export every X minutes to user defined folder, keeping most recent Y backups - chrome.downloads API
   • Automatic Sync every X minutes

   User defined folder option would introduce many validation checks as the path cannot go back (must be a sub directory of Downloads) as indicated here

4. Filter

   • Textarea that lets user input which sites to exclude from TabMerger
   • The following websites are excluded from TabMerger (default chrome:// and new tab)
   • Wildcard Glob & RegExp patterns, eg: http://www.*
   • Test input into which the user can type a URL to confirm whether or not the filter works.

5. Keyboard

   • Enable/disable switch
   • Shortcut list with description: Alt/Ctrl + Key <description>
   • Link to shortcut menu: chrome://extensions/shortcuts

Dev Notes

• The above tasks are solely for the UI portion, a separate ticket will be made to handle the functionality!
