[Beehive Pro] Use Select2 for dropdown selections/lists

Select2 (https://select2.org/) for the dropdown select box when selecting the GoogleAnalytics profile.

Would be nice when you start typing only matching GA profile’s show up.

When having a lot of sites in GA it’s a long list, with all the https:// and UA- stuff ad the end it’s kinda difficult to find the site you need.
Select2 would help a lot. better yet suggest the profile that matches the domain.

Should/could also be implemented for all other plugins that uses dropdown selects.
