Add icon fields as a column type in table fields

[MoritzLost]

It would be great to have the icon field as a column type in table fields. Picking an icon for a row is very useful for dynamic content, like a field for icon teasers, where you have two columns for a URL and an icon.

As far as I know, icon fields only store the handle of the selected icon, so it should be compatible with the storage format for table fields.
