Download this, copy the folder into your project, after the copy and recompilation you will have "FolderIcons" file appear in your "Assets" folder. Click on it and add folders you want to modify. There is a small plus button that adds three fields after you click on it - place the folder into the first field and the new texture in the second field. Repeat for each folder you want drawn.
