Add modes that should be ignored by golden-ratio

- ediff-mode: this is the small one-line panel at the bottom when using
  ediff. Should not be messed up.

- gdb buffers: this should not be messed up in a gdb-many-windows
  debugging session.

- Dired buffers don't need extra empty space, so is speedbar and bs-show buffer.
