Fix and improve ido module

- ido will actually be loaded at startup - I'm hoping there's a better
  way to optimize this.
- ido-sort-mtime-mode was fixed
- Up/Down were added to get closer to
  `(setq ido-vertical-define-keys 'C-n-C-p-up-down-left-right)`
- Faces were re-enabled
- The number of results are now displayed with ido
