SpriteMaterial node file list doesn't refresh when new files added to directory

If you add new sprites to the directory while the editor is running, the file list won't update until the project is re-opened. Possible fix: add a refresh button, or dynamically load current contents of directory when opening the material selector panel.

It appears that adding new files via file system is not the recommended behavior - all new files should be dropped into Explorer within Talos
