Feature request: In data sections, display data with relocations differently

[muff1n1634]

For example, instead of a function pointer with a relocation being shown as 00 00 00 00 in the data view, it would be shown as xx xx xx xx (doesn't need to be x) to visually indicate that there is a relocation associated with it. This would distinguish it from the zeroes of an integer type, floating point type, padding, etc.
