Use Font-awesome for burger menu and arrows

[rcass]

Since you are enqueuing font-awesome I would use it to your full advantage.

You can find a svg replacement for the hamburger menu and arrows. That way you don't have to have those images in the images folder (yay the theme will be lighter) and the svg are nicer to scale of course

burger-menu.png and other unused images in /lincedge/images will be removed together. I didn't find a font-awesome icon arrow that matches the current design.

aww dang, I would just take one of the arrows and turn it the right way to match.

For example:
https://fontawesome.com/icons/angle-down?style=solid
