Clean Up Find Replace Overlay Icons

- The icons are part of a local toolbar. Therefore move them from the
  "obj" folder to the "lcl16" folder.
- Fix file name for high resolution icons for select_prev and
  select_prev icons
- Make more clear what's the file name of and icon and what's it's key

Fixes: eclipse-platform#1977
