Fixes the underlying issue with the material overhead stats.
Usage flags for the material were set from outside the material editor. I needed to update the overhead stats materials to match.

#add Added UEdGraphNode::GetNodeNativeTitle to return a native title for a node.
#add Added UEdGraphNode::GetNodeSearchTitle to return the native and localized title for a node, together, for searching.
#add Can hold "alt" over a node (in the graph panel, or the palette) to see the native name of the node.
#ttp 331252 - Blueprints: Editor: L10N: Blueprints need to consistently show localized node names and when searching need to search both the localized name and the native name

#proj UE4.Engine
#summary Added Find Results tab to Material Editor
#add Added SFindInMaterial class to search and display results from materials, similar to the Blueprint version but didn't seem like there was an obvious method of splitting it up into a base class that could be used by both. Made sure to use the search functions from Material Expressions as well to ensure that the results will be the same or better than they were previously.
#change Added new function to UMaterialExpression to get a one line description of it. Most of the time this is just all of the expressions captions combined into one line using spaces, though there were exceptions for constants, textures and function calls so that better information is shown in the results window. Also added a JumpToNode function to FMaterialEditor so that the find results can show the nodes when clicked on.
#extra This is only for searching the current material at present, adding support for searching all assets would be a lot more work as we would need to store meta data allowing materials to be searched before they are loaded.
