Add flag for icon type (FA, BI, etc)

[derikb]

Currently using Font Awesome 4 (since its the last free one), but the code here is setup for some specific > 4 FA classes and styling:

• fas doesn't exist in FA4 (removing "s" fixes)
• fa-sm in combo with the -1.625rem left margin on the search filter causes the search input to hang over the left edge of the dropdown. (removing fa-sm fixes)

Would also be good to add support for the boostrap icons (since they are free to use), which should be pretty minor.

This could be done with templates, but with the increasing use of the bootstrap icons with the BS5, it might be worth simplifying it for users. Maybe just a option that will auto-adjust the 2 templates to use different icon sets.

All versions of Font Awesome have both a free and a commercial (Pro) license. Not all Pro icons are available in the free version, which is the only limitation of which I'm aware.

idk, there's some reason my company told us to stay at FA4 (maybe there were icons we were using that turned pro only).

Either way my point about an option for the Bootstrap Icons is relevant (and fairly simple to implement).
