Update IconPacks - Remove unused icons from FontAwesome

[nhurde]

In order to be more seamless and have users of the editor able to change iconpacks based on folders/zips it will be important to limit file size of actual releases. There are some icons in the fontawesome pack that are not used and should be removed.

If possible, to keep all iconpacks synched some icons can be renamed or a structure created to translate which icon name goes to which actual icon in editor.

Not crucial as simply for more customization, but should be hopefully done by 2025.
