* Changed Ld rule to allow adding resource files.

* Changed ResAttr rule to allow not deleting the file before writing the
  attributes.
* Added application signatures for the runtime_loader and zbeos, just so that
  they may have an icon, too (hint, hint) :-)
* As a side effect, this also let's FileTypes handle these two as apps (even
  though they aren't), so that I can close bug #606.
