Fix/material paths

[beersandrew]

• Updated emHdBindings files with a change here to add the fully resolved path of the asset as a parameter back into js
• Used the new resolvedPath parameter as the field to get the file path from
• Removed code used to search through the file tree to figure out the correct path on the front end

Super cool to see all that hacky code go away!
