Compositor Nodes Distressed edges Chipped paint

New compositor nodes:
Distressed edges,
Chipped paint,
Erode/Dilate w/controls,
Height2normal

Here's an alternate method for bump using height2normal and the normal node.
Distress edge to well distress the edges of a clean mask.
Chipped paint to animate a chipped paint effect in the center of the text.
Distressed edge and chipped paint I created from scratch.
Erode/Dilate I created from scratch to expose controls. It's not as accurate as the native node but I wanted the control.
